"Samples From Mars" (SFM) does one thing perfectly: they buy the hardware, max out the memory, and sample every single sound at 24-bit. Their R-8 From Mars pack includes all 6 ROM cards (Rock, Dance, Latin, etc.). They also provide a "Lite" version and a "Raw" version. They frequently sell the entire Mars catalog for $39, making this the best bang-for-buck.

The R-8 snare begs for gated reverb.
