You're going to get several different answers here. They are all good trucks, and each have a following. I'd have to say that there are probably more Savage owners here than LST or MGT owners. Having alot out there is good for spare parts. There are ALOT of folks on eBay who part out new vehicles, and you can usually get spare parts considerably cheaper than buying packaged HPI parts. The Savage also has a TON of after market hopup parts available, probably more than the LST and the MGT combined. Although If you get a savage I'd be cautious not to be tempted to the dark side and start slapping aluminum parts all over it. They are horrible for bashing as they bend. The same goes for the LST and MGT as well. Aluminum looks pretty, but it's bad idea for a vehicle you will be bashing.

One thing to remember about the extra large versions of those monster trucks is that while they are more stable, they are less nimble. Even with the larger engines, don't expect any of those vehicles to pop wheelies like their littler brothers.
