Swap meets can be pretty good. One of the local clubs had their annual swap meet in November. Someone was selling a GP Patriot 40 for $90~$100 CAD. One of the newer members of my club commented "Yeah but you still have to cover it.". I needn't have the cash for it and I don't believe it ever sold. Have to check one of the other clubs swap meets in February.

I've never found a better deal on kits, engines, or ARFs, than RC swap meets. I don't know about your area, but it's very common in Florida, for a fraction of Ebay prices.
