That would cost around $180? so not to bad.

I found a set of UE 8 Spyder for $175 from a guy at my local hobby shop they looked good and he said there is nothing wrong with them. Is that a good deal? What's the differance in the UE 6, 8 Spyders anyway? I went to there site and a lot of things seem to be out of stock.
