RE: wich is a better buy
The Savage 25 is the base model of that line...
If you really want the fair comparison of these three trucks, use the 4.6SS version with nice electronics. The prices and specs of each package would then comparable. That's all Losi and CEN did with their trucks, and that's why they cost so much more. They offered the nicer kit level engines and radios in an RTR.
I would choose either the Savage or LST2. The LST2 is probably better out of the box.
