Sabrepulse
I'm not much of a fan of his stuff, aside from the remix of As Vivid As Possible. That track, however, makes up for the fact that I don't really like his other stuff.
If anyone's into chiptunes, definitely check out 8bitpeoples.com. Tons of free downloads. I highly suggest Nullsleep, Random, Vim, x|k, and Xinon (!!). I haven't downloaded stuff from everyone there though, so I could have missed a couple of great artists.
Also, look for albums released by the Ay Riders, they've made some pretty wicked remixes.
And don't forget to download every song ever made by Rob Hubbard and Tim Follin.
