I would definately say the Savage X SS. It is one of the most durable trucks in the industry, and you'll have a hard time breaking it.

You will also need to buy Electronics, and there are many different manufacturers and types. A 2-Channel System is all you need if you don't want reverse, and a 3-Channel System is required if you do want reverse (you will need the reverse module in addition to that). It all depends on your budget.
