EXS 24 Logic Sampler Users Group

Does anyone know a good source for folk/blues fiddle samples 
for the EXS? I'm looking for something that evokes the vibe of 
Sugarcane Harris (Hot Tuna, John Mayall) and/or Hugh Marsh. I 
have the American Heartland CD from Sonic Reality; the fiddle 
sound there sounds like an afterthought--not usable for much. 
Ideally, I'd find something with a good multi-sampled instrument 
and some loops and phrases. I figured if anyone knew, it would 
be someone on this list. Thanks.
