I used to be all over a ton of those sites when I first started out with this before I got my Triton, but I can't remember any of them. I remember a few months ago, I was searching for sound effects samples and just typed that into Google and got a ton of sample sites though. Another is my boy, Ghetalion, who used to have a sample section on his site (www. ghetalion.com), but I don't know if he still does.
If I come across any, I'll post them for ya, though.
