As far as I know, you're lucky if you can find one for under $250. I've seen them on E-bay for around $230-$250. You might get lucky and find one if you hunt around a bit. You can get a 1/16 RTR nitro buggy here for $279.

To be honest, I think these are over-priced, but I guess that's the way it is for all of these new designs.
