What HP calculator should I buy

[Logan]

After being in a similar situation last year, I settled on the 42s as pretty much close to my perfect calculator, though I wanted a smaller package than a graphing calculator. If I want to graph stuff, I'll use MATLAB.

The DM 42 should be coming out soon and it promises to be fantastic. The 35s has some good quick and dirty programming, but you're really limited on variable names.
