TI Nspire or Casio Prizm?
Or something else?
I want a calculator that I can use to get 6th form on board with using calculators well - the TI-81s and 2s we have around the place don't impress.
(Does the Nspire do numeric simplification yet? Can it simplify "root 8" to "2 root 2" like £5 casios do?)
In answer to your question the Nspire still doesn't handle surds (I'm told this is something to do with US exam regs), which is annoying! But it makes up for that in many ways... You can download a 30day trial of the software to have a play with from the TI website which will give you an idea of what you can do with it.
The Ti-Nspire is a pretty nifty calculator. Its more powerful version, the cx CAS will do surds. Perhaps that would be a suitable consideration?
The 'CAS' bit implies to me that it wouldn't be allowed in a UK exam, however (I don't know as I've not checked its functions).

I would suspect almost definitely not!
