You can find lots of reviews on Mystery's forums, ASF, etc. Of course, there is sometimes a debate on whether the reviews are authentic, written in the glow of bootcamp state, or peer pressured by various instructors.
I don't personally know people who have taken every single bootcamp, and even if I did there is some chance they could've been having a bad weekend, gotten a poor instructor, or some other circumstance that negatively effected their perception of a particular boot camp.
Other things I think worthy of considering is what you want from the boot camp. By the time you add in airfare and misc. travel expenses, the initial price difference might mean less anyway. Do you want theory drilled in your head? Do you already have the theory and need help inplementing it in the field? Do you want to see firsthand how a top PUA works? I mean if you're only comparing just the bottom line price, then you might end up paying for something that isn't even what you wanted.
I think if it were me, I'd also sign up for ASF's PAIR wingman finding system or join a local LAIR. This way you'll have some friends to keep you motivated when you get back. Unfortunately, you will meet some people who will jst pull you down. I know I have, and I am not shy about letting people know when they are bringing my state down or otherwise interfering with my success. In this kind of game, you really have to be assertive to get what you want. At the very least I'd consider joining toastmasters to keep up the regular public speaking. Sorry, I'm going off topic here. OK Im way off topic but I got to add that the best times of my life were probably traveling in exotic places, I also got the best stories that way which helps me with women all the time. If I had to pick only one or the other due to time constraints, I'd choose that trip to Peru over a bootcamp anyway. By being that guy, you really don't need much more to draw women in. Just my .02
