HP 17bII+ Silver solver

[rprosperi]

If you want to really explore the capabilities of the awesome Pioneer Solver, and confidently try to push it without worrying about using L() this way or that, I agree with Don, buy a 17BII and use that for the Solver stuff, but continue to use the 17BII+ for every day stuff.

Here's a very nice 17BII for only $25 (shipping included, in US) and you can even find them cheaper if you're willing to wait:

The 17BII is bug-free for solver use, while the 17BII+ has a much better LCD, readable in a wider range of lighting & use conditions.

In case you haven't seen this yet, here's an example of what can be done with the solver:
