EXS 24 Logic Sampler Users Group

I'm thinking of ordering several of the ProSamples CDs and wondered 
what people think. The East-West site says they're cut-down/cut-n-paste 
versions of other sample sets, so I'm wondering what people think.

In particular, I'm looking at:

Volumes 11 (Classic Orchestra), 13 (Choirs), 18 (Steinway), 22 (Hip 
Hip), 30 (World Instruments), 41 (Solo strings) and 43 (Real Drums).

Comments on sound quality, versatility are welcome as well as how 
well-done the EXS implementations are. (Actually, I'll be using EXSP24. 
Can I assume that EXS-format instruments play the same even though the 
EXS24 seems to have more controls?)
