I got a HP 17Bii, and I love it!

Oh, and don't forget the 17b. The main difference between the 17b and 17bii is RPN on the ii, but if you mainly use the solver RPN makes no difference. I have two of each. The 17b has a certain beauty to it. Speed of execution and solver functions are the same in both.

I had a 19bii years ago but its solver suffers from a fatal flaw (to me at least): you can't save a solver equation you are entering if it contains any errors. You must find and fix all the errors before you can save it, which is very hard to do if your equation is large. The solver on the 17's don't have this problem.
