In my own opinion....I think the EMaxx is the best electric 4x4 truck made. I own one and am very impressed with it's performance. It has such brute power that it will flip itself over from a stand still position. It also has a two speed transmission which enables it to reach speeds around 30 + MPH. It handles like a dream....is a very tough truck....has an awesome paint job....good suspension. Also....realize that it takes two 7.2 volt batteries to run it so your going to have that cost also. And along with that you'll also need a battery charger to keep your batteries charged. If you decide to go with the EMaxx let me know as I have a good link to a source on eBay where I buy all of my batteries.
Good Luck!
