That's a good point, there should be a sticky for that. Off the top of my head: FA, CMMRS, UWorld Qbank, Goljan RR or BRS Path (80+% on here use Goljan I would guess), Kaplan or RR Biochem, HY Mol/Cell if you can find it, HY Behavioral Science, BRS or Kaplan Physio. These aren't necessarily what I'm using, but I think it's a pretty good generalization of the advice you'll find from doing a search, which I also recommend.
