I'm reading secrets (which is basically the same as Crush, but different format, both written by Brochert). Some of the sections are nice, but others (Peds, Psych, OB/GYN) aren't so good and I turned to First Aid for those sections and it was MUCH (I repeat MUCH!) better than Secrets. I wanted to focus on Secrets since it's a quicker read and easier to master (leaving more time for questions), but it has some sections that blow, in which case First Aid comes in handy. There's a new edition of First Aid (copyright 2006), which is about 350 pages of reading and $40-45 brand new. It's hard to consider money spent on FA a waste, so I'd recommend buying it anyway. Good luck!
