I've bought a few sample cd's from Ebay, some were crap, some were good. My best one is a cd with all the old drum machines .wavs. About 15 roland machines, Korg, Casio, Yamaha, Alesis and many more.. paid about $10 for it. When it comes to drum sounds, anything is good. I have not hear a drum machine/keyboard that had sound which didn't require any tweaking. If your looking for something like that, you'll be searching for a while. Sure you can buy sounds from S4S and shell out some bucks, but you can also create the same sounds from those generic samples that you guys hate. Generic or not, if you layer a plain snare with a clap and a plain cymbal, it ain't gonna sound too generic anymore..naahmean? ANd by the time you put them same sounds through the mixer, adjust the levels, them same plain sounds will be like the same thing you would pay for.
PS.
S4S does have some nice sounds, so I'm not trying to shyt on them.
