I have used the Sonic Implants Drum Implants in soundfont format and found them to be a great sounding buy for the money. I would expect their giga stuff is of similar quality. Also, thanks for alerting me about their giga sounds.
I just ordered Small Ambient Two. I must say it is awesome. Best giga drums CD I have and it was only $24.95 to download. Great real acoustic kits - 4 or 5 snare/kick variations. And a bunch of kits with smaller snares and filtered. I\'m blown away with the quality. I hooked up my KAT pad and I swear I was playing a well miked kit.
