I would like having this myself, but I've not seen any 17bii simulators, unfortunately.
There were, however, a number of devices produced by HP that feature the same HP Solve:
17b - Probably the cheapest option, but missing L() and G(). (...and RPN!)
17bii - Same as the 17b, with L() and G() added.
17bii+ - Same as the 17bii, but there were some changes that cause L() and G() to behave differently. I'd stay away from this one.
18c - No L(), G(), or looping.
19b/19bii - Includes trig functions, I believe.
22s - Has trig and scientific functions, but no finance, and missing L(), G(), and looping.
27s - Same as 17bii, but no cash flow lists, and it apparently only uses iteration, not algebraic simplification.
95LX - About the same as the 19bii, plus you can back-solve in Lotus 1-2-3. Can be found cheaply from time to time.
100LX - About the same as the 95LX, but some ROM versions have a bug with reading cash-flow lists.
200LX - About the same as the 95LX, but no bugs that I'm aware of. Most feature complete, but can be pricey.
OmniGo - Pretty sure it had the same solver, but was missing some features.
There was also a Windows (3.1) version for some older models of OmniBook, I believe.
You might also consider downloading one of the 48GX emulators for iPhone/iPod. The 48 has an algebraic solver that's somewhat similar to HP Solve, but without L(), G(), and looping.
