I've heard Ez drummer claustrophobic, but I don't think that's what I'm looking for. I've heard Stylus RMX as well, and I know it got some great Lo-fi drums out of the box, but I'm hoping there are other alternatives.
WAV/Acid loops are ok too if there's any...
if you want a drum kit you can program in a variety of styles, then Superior 2 is great. Much more flexible than the EZ drummer packs, although you can use those with it as refills.
If you get S2 and add the NY refill you will have a very wide variety of sounds.
Lo-fi is narrow bandwith and distorted, like a gtr amp.
I recommend checking out the micro-packs on Puremagnetik. (In case that previous company name is not allowed, then search micropacks on google, and you should find it. Or PM me.) They sell in Ableton form, Kontakt 2, and something else sometimes that I've forgotten. Price is right.
Also- anything from Loopmasters- they have a bunch of downloadable things as well- REALLY nice quality.
