for classes, lippincott is the go-to book. for boards, kaplan's book is great 'cause you can get through it in 2 or 3 days and it has very clear explanations and integrations. HY cell and molec is also highly recommended around here, and i've liked what i've seen it in so far. i'll be using both.
so, looks like we have a lot of consensus. i've peeked at RR, and it looks good, but i don't think i'll have time to go through it. i've already done kaplan's books once through, so i figure i'll stick to it (familiarization is key for review IMO).
anyway, thats my $.02. good luck
