I like Predator camo the best. You can check them out at
http://www.predatorcamo.com/index.html I recently purchased a set of Spring Green for the early seasons and turkey hunting. I'm going to get a new pair of bibs in Fall Brown from them real soon for the later season.
However, if you want to just get into something quick and easy, go to your local military supply shop and pick up some military camo. It works just fine and is pretty cheap. For $50 you could get a bunch of good clothing.
You can also just order whatever you need from Cabelas or Bass Pro shops. The actual patterns don't matter much. Just a personal preference really.
