Hello, the xtm x cellerator seems to be good. My step son has one and I have seen it run. It goes very well and jumps great. I own a nitro evader st and broke it where his xtm didnt. It seems to be quite durable. He has only driven it a couple times. Today he broke it for the first time (the rear suspension plate). It broke because he hit a pole so it wasent because it was weak. I dont know about the parts yet as he is just starting to look for some for the first time. If you know where to get the parts and at a good price, let me know.
