In a way I'm jealous of some of the folks reviewing HP's calculator line who have tried virtually the whole line of HP calculators. But then in a way I'm not because I found the best one right off the bat. I did have a 22S before my 32SII, and was very happy with it, but when it came time to replace it with this one I soon found that I had made an excellent choice. And now when I'm looking for a new one (just to see what's on the market, mind you) I see that HP still hasn't topped this calculator, judging from the reviews on the new ones. I'll never sell this baby; it'll stay right by my monitor at work, ready to quickly and effortlessly run numbers for me. I particularly like the keys, which are solid and have a good feel to them. This is a quality calculator.
