Still quite reasonable prices for a verygood to excellent working model on various web sites. The 20S and 21S are pretty cool models, and two of very few programmable algebraic models from HP, but I probably wouldn't use them for very dataheavy statistics. The 21S does have quite a few builtin distribution calculations (normal, student's, F, chisquare), so if that's a large percentage of what you need, it might be a good fit. But it doesn't do listbased statistics, and it only has linear regression built in (unless you program other models yourself, or manually transform data before entering). One of the neat features of the 20S and 21S is the builtin program library that lets you load a few prewritten programs into memory. The 21S, according to the manual, has one and twosample test stats, linear regression test stats, chisquare test stats, binomial probability, and TVM. The 10BII+ might also be worth considering, as it allows for a small amount of listbased data, and has more regression models, though it's lacking F and chisquare distributions, and obviously isn't programmable.
