I guess it all depends on your size and style of flying, 1/2A is cheap, 1/2 scale isn't so. But I've seen some rare .061's go for 1500 bucks. I spread the wealth amongst all of the sizes, form 1/2A to 1/3 scale gassers, I found that I spend a whole lot less on my scratch built small planes and roughly 1600 on the largest size planes. But the really exspensive ones are the 60-70 sized scale jobs, add all the details and retracts with glassing, paint,...ect. You end up with a hefty bill and a nice plane, of course this applies to the kits, not ARF warbirds that come predone in the box.
