I know, rainbow tables are a little out of style in the days of gpu cracking, I still prefer them though....especially with unsalted MD5 I always got faster results than with gpu cracking (ok, this of course depends on the gpu, cpu and hdd).
anyway, here's a nice collection of rainbow tables, my box is already running permanently since 3 days to download them......make sure to have a bunch of terrabytes of free space if you want to get them all:
