EXS 24 Logic Sampler Users Group

Hi! I just bought the platinum24 Grand, the Percussion and Mixtended 
drums from Wizoo (the cool bundle for exs users)
and wanted to ask for any more "must have" stuff for the building of a 
library. I got lots of free stuff, the akai stuff from the japanese 
Server, the three emagic sample Cds, but what else can you recommend 
(apart from The Vienna stuff, which is not affordable for me at the 
moment)?
Thanks for any Tips!
regards, Frank Valet
