I did not suggest the Hp17B or Hp17Bii, I suggested the Hp19B or Hp19Bii. These are business calculators with trig functions and units conversions.
The Hp15c is a well made tool that is appreciated most by EE's or others with a need of complex number, matrix computations and possibly numerical integration. If you don't need these features, the Hp11c or Hp32s do just as well. To get the above on an Hp41, additional application modules are needed. That is the charm of the Hp15c over everything else except for the Hp42s or an Hp41c with an advantage pac module.
Simply put, the Hp19Bii may be worth looking into for an easy to find RPN with all the niceties of the 27s (same calculator from a functional point of view aside from the lack of HEX, OCT, BIN, Dec conversions, and no algebraic precidence in algebraic mode).
If you do like RPN, the Hp 48G (older and easily available for not a lot of $$$$ on ebay) is an excellent choice. Nice Hp feel, kind of bulky, but has a great solver w/ all the features of the Hp27s as well as many more. If you key in your own programs or equations, 32K is a lot, if you buy a cable and download, 32K don't go far. But you can download a couple of decent programs and with all the built in features, it is a graphics that will last a long time. It is slow in graphing compared to the Ti line, but I don't use it to graph functions anyway. The newer Hp's are far faster, but aren't of the same quality and the new Hp48Gii doesn't offer the built in equation library of the older Hp48G either.
