best MT manufacturer?

I wanted to get my son into RC, so I got him an RC18T. Within 10 minutes of getting it, he broke a shock; and that was just the start of it. Then I got him a T4, he kept breaking arms. What can I say? He's 8 and has too much of me in him. The last thing I gave him is a Monster GT that I converted to brushless. I made it first gear only. The whole truck is stock, including the steering servo. The only thing I did to the tranny was the first gear thing and I took out all of the reverse plumbing. He's been running it a couple of weeks and I haven't had to replace anything but a 2nd gear shaft and a couple of rod ends. In my book, it's the best because it does what a monster truck is supposed to. It goes over, through, or up just about anything that gets in its way.
