Suggestions for HP41C Message #1 Posted by Dimitri Simitas on 6 Feb 2010, 10:06 p.m. I was wondering what you would all consider a fair price for a good working HP-41C would be? Also wondering the availability of the Machine Design, Stress Analysis pacs and the Mechanical Engineering, Physics and Fuild Dynamics Solution Books? I'd be looking to acquire this over the course of my mechanical design program. So no real rush, I would be starting with the calculator though as the rest require it for use. Thank you in advance. Dimitri

Many "fair price" discussions are found in the forum archives. Eventually, a "fair price" for an object depends on the buyer and his/her desire to own said object.

The pacs show up every once and a while on TAS. For the books, please find the answer here together with lots of other interesting information, saving you many bucks d:-). I strongly recommend this DVD if you're willing to read. HTH Walter

Thank you for the quick reply Walter. I've been watching Ebay so far, but I realize sometimes Ebay is not a clear indication of market value. Calculators are not like cars that have a "Blue Book" value making it easy to establish a base price and go from there. Yes I know of the DVD, and it will be ordered shortly, just waiting on my paycheck. I hate running a balance on my credit card. Dimitri

IMO, eB** is the best indicator of market value, with the proviso that the market is the worldwide universe of collectors and users who are "internet comfortable". Of course there are many other markets, and eB** may indeed not be the best indicator for those markets.

Re: Suggestions for HP41C Message #5 Posted by Dimitri Simitas on 7 Feb 2010, 9:43 p.m., in response to message #4 by Martin Pinckney I don't know, Ebay makes prices increase in my mind due to the ease of access for the items. None the less my post is now more academic, ordered the HP DVD and a near new looking HP-41CV from Ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=280462429141 Dimitri

Where buyer and seller can easily find each other, and can freely enter into a buy-sell agreement, and throw on top of that multiple transactions of similar items, to me that defines market value. Local markets may vary, however.

Re: Suggestions for HP41C Message #7 Posted by Frido Bohn on 8 Feb 2010, 3:24 p.m., in response to message #1 by Dimitri Simitas Hi Dimitri, just finished to buy an HP41C via an e..y-auction. I was pretty lucky that the guy sold it as damaged, but it resulted to be in perfect condition. The seller obviously avoided to use the right kind of batteries and failed to test the 41 adequately. The price for which I finally won the auction was 41.41 Euros - the only price for which an HP41 should be purchased - that is about $58. I would estimate from my observations in the German area that the usual price for an 41C is about $150, for an 41CV about 200$, and for an 41CX about $350. All being in a fair mint condition. Regards Frido

Re: Suggestions for HP41C Message #8 Posted by Dimitri Simitas on 8 Feb 2010, 5:43 p.m., in response to message #7 by Frido Bohn Thank you for the reply, in Canadian dollars including shipping I got the HP-41CV for just under 200$ so I think I did good. That is a pretty good deal for that calculator of yours! Dimitri

Re: Suggestions for HP41C Message #9 Posted by Aldo Luis Molinari on 11 Feb 2010, 8:19 a.m., in response to message #1 by Dimitri Simitas Dear Dimitri: I am looking for an excellent Card Reader for my HP41CX; could you tell me, please, where can I buy it. I have more than 50 navigation programs and I can't charge into my HP41CX because the card reader is out of service. I live in Argentina, Buenos Aires. My email is amolinari@sgp.gov.ar or alfalima@fibertel.gov.ar.- Thank you in advance for your consideration.-

Re: Suggestions for HP41C Message #10 Posted by Dimitri Simitas on 11 Feb 2010, 12:59 p.m., in response to message #9 by Aldo Luis Molinari I have seen a few on Ebay the last little while however I do not have one myself yet. If yours stopped working check Ebay there are repair services available. Dimitri

Re: Suggestions for HP41C Message #11 Posted by Frido Bohn on 11 Feb 2010, 3:50 p.m., in response to message #9 by Aldo Luis Molinari Hola Aldo Luis! I would strongly recommend to look for a repair of the card reader. Typically, the gear roller is worn down after so many years, and a "new" card reader could develop the same problems. If you look at the Repair Instructions for the 82104A Card Reader, you may feel encouraged to do it for yourself. I have done this for myself, and thereafter the device was fine as ever before. Saludos Frido

Re: Suggestions for HP41C Message #13 Posted by Dimitri Simitas on 13 Feb 2010, 8:02 p.m., in response to message #1 by Dimitri Simitas I purchased the Machine design module on its own. As well as a ROM card folder and memory card for my HP 41CV. I am getting there. Dimitri
