Yes, go ahead, it’s a good opportunity! The calculator is very capable by itself, I just cannot stand the algebraic system but with the RPN aplet that issue is fixed

There are plenty of unused units in eBay, below US$20 in some cases, I got mine from this seller:

The units I received were unused with minor scratches here and there but because of the cover the front was in perfect shape. One of the units I got the “2” key was not working well but seller shipped me another unit at no cost, the seller even paid for the shipping, so no complaints.

Manuals and batteries are not included, though. The USB cable is a bit short but those are very easy to get.

Happy New Year.
