RE: Monster Truck for a beginner...
It's really great to read a post where money is not the deciding factor. Way too many where someone is trying to get a truck with a $300 budget. Anyway, I think you will be good with any of the big name trucks. You might also check your local hobby shop to see just what they stock, and to get your hands on the trucks and see which one you really like. Take a look at the Revo, Savage X, LST2 and MGT 4.6. I think either of these will put a smile on your face and you should be able to get parts most anywhere.
Have fun shopping for your truck and let us know what you get. With pictures of course.
