PM all AVers in your area, very few will respond :\
I'm use hiking boots atm and they are pretty awesome, never had to think about my footing or throwing out my ankle. Didn't have to worry about my feet sweating too, I HATE SWEATY FEET!! ARGH!!
Got my first primary off classifieds too so you can make your 300 buckeroos stretch out a little further if you do that, after you get AVed that is...
last thing...make sure you buy a gun to match what where you play, don't get a bolt action sniper rifle for CQB, no one will let you in... factor in how much it would cost to change the FPS of the gun too
