While I have never paid $500 for a sled, I can't say enough good about the 340 Invader. I had mine out yesterday and it is a blast to ride. Generally I don't have any problem finding parts for Invaders and Intruders - LTDs and Interceptors on the other hand can be more of a challenge - but with time and patience just about everything that you will need is still available as used, NOS, or aftermarket. Good luck.
