Good ripping program - no compression

I'm thinking about buying a 200GB external hard drive a ripping about 300-400 CD's to it. I do about 80 percent of my listening while sitting in front of the computer and am getting tired of shuffling CD's. I'm looking for suggestions on a good program to rip with but I don't want to use any compression as I wish to compromise the sound as little as possible.

System:
P4 2.8ghz
M-audio revolution sound board
monarch SM70 class a amp
B&W LM1 monitors
B&W sub

Thanks,
