Your best bet is to do a search on this website... this topic has been discussed tons of times before... but here's my $0.02
I didnt' take any review course at all. NSUCOM offers Youel's review, which I did not go to, nor did I take the Kaplan COMLEX review course, which many of my classmates did. I bought the 1999 Kaplan USMLE books (you can probably buy it on ebay) and pretty much used those as well as the Board Review Simulator Series (or something of that ilk). I also glanced at Step Up and First Aid, but they were only about 5% of what I studied timewise...
hope this helps.
oh and I used Savarese for OMT.
