I have owned all of the MT's mentioned in this thread at one point or another. from the ones mentioned I would recommend the Losi XXL or the MGT 8.0 over the Savage XL. the XXL is probablt just slightly better quallity of the others especially when you consider the radio gear and engine that it comes with. The Losi 454/LRP.28 is an awesome engine!! HPI' 5.9 leaves something to be desired it doesn't tune as well as the others and many people say just sell it before you ever put a drop of fuel in it and buy a different engine right of the bat. The MGT is probably my favorite MT out of all the ones I've had. the engine was great! it has a very wide tuning window and was one of the easiest engines to start I have had. the only issue I had with that engine was that it is a gas pig. you will go through fuel in a hurry with it. the MGT 8.0 is huge, loves to do wheelies, is quite fast I never gps'ed it but I would say it falls into the mid 40MPH range. What set it apart though from the thers it that it is easier to work on. you don't have to tear half of the truck apart if you want to get to the diffs or the tranny like you do with the Savage or Losi.
