I'm not sure how many of you have been to this site but if you are looking for RC stuff to buy/sell I get most of my items from here. Just your standard online garage sale for people to buy and sell their stuff but it's very popular so there is a ton of stuff up there. It's a pretty large RC site in general but I only go to this single thread to buy and sell stuff. Be warned, you could get hooked pretty fast! HAHAHA
