EXS 24 Logic Sampler Users Group

I was speaking to a tech at Big Fish Audio.  They have an Acoustic 
Piano CD for $200 in S1000 & S5000 format.  I got the impression 
from him that the EXS24 would only import the S1000 - and that the max 
intrument size was smaller for the S1000 (they advertise a 250 MB 
version of the Yamaha C7).

I only have a single SampleCell CD - and am looking to purchase my 
some addition instruments - but I'm unclear about Akai samples.

1. What is the max size of an instrument on the Akai CDs? (if the cool 
instruments are 250 meg, I'm going to need to get more RAM)

2. Can we import the S5000/6000 - or will we be able to in the near 
future?

3. Are the Big Fish Audio CDs good quality?  Thanks, Les Caudle
