For the last 3 years my workhorse calculator (mostly doing electronics work) has been a Casio fx-260. I love it because it's small, and does most of what I need very quickly. For the odd occasion where I've needed more I break out a TI-85. I've decided to go back to school, and want a new calculator. I'm not sure I'll find anything I like better than the fx-260, but I figure I should give myself the chance of finding a better tool. I'm certainly not opposed to having nice features like unit conversions and constants and registers/stacks etc.

At first I was looking at the FX-115ES, and came close to buying it, but was lured towards the HP 35S because of the RPN and programmability. I can live without RPN, but I really would like to have a programmable calculator that fits in my shirt pocket. I've decided against the HP 35S because of the lengthy list of unfixed bugs that appear to have been around for many years now.

I see on the international Casio website that they have programmable scientific calculators, but I don't see any on the US site. Why is that? Are the fx-4500PA or fx-50F Plus any good?

Two things that are very important to me for a calculator are rectangular/polar conversion (another strike against the 35S) and fractions.

Thanks.
