RE: first look into nitro
LMAO wow $160 for nitro. Man that's pretty funny. Oh and yea I must say going used is smart as well! For $140 (less than the price of your "exceed") I got a RC10GT with an extra engine and parts.. found it right here on these classifieds. Take a look! Some nice RCs for cheap on there. They have RS4s all over the place last time I looked around the $150 range. Crazy. Of course, the engine may not be as good as a new one.. but just get a new OS engine for about $100. And some of the RC makers (HPI comes to mind) have engine trade-in policies (HPI lets you trade in a crapped engine for a new one at half price!). So, say you score a RS4 for $150, trade in the engine in HPI, get a new one for like $75.. and there you go, good as new RS4 for $225. (Applies to all HPI RCs like firestorm, obviously.. I just find RS4s all over the place for some reason.)
I saw a Firestorm 10T the other day on there for $100 :O
