Re: Who designed HP 17BII+?...
Dunno who designed it, but I reckon right now its the best CURRENT
financial calculator. I've been evaluating all the ones I could find
and it fits the bill. I was able to program MIRR into it rather
easily using a solution from the 19B manual. The TI has MIRR already,
but the quality of the actual buttons and stuff is inferior to the HP
and it doesn't have a solver. There are some known bugs in the
latest rev of the 17bII+ in terms of the solver, which is
dissappointing, so hopefully HP will come out with something better in
the future. If they still made the 19B I would get it. It has a few
more functions available in the solver which are not in the 17B, such
as trig and PV, FV, etc. But you can write solvers to do those
things, but you just have to use lower level functions and its a bit
more tedious and complicated to figure out.

If HP would make a new calculator that had solver, financial
functions(including MIRR for crise sakes), macro programming, trig and
some additional scientific functions...I would buy it tomorrow for any
price. But until that time, for real estate investing...the 17bII+ is
probably the best calculator currently sold. That's my opinion.
Anyone know of anything else? is there a higher end calculator that
does everything the 17B does, with all the other stuff as well and not
too complicated to use?

You can calculate the trigs by using the solver. Different formulas are
given in this article:
