The evader is a very cheap (but decent for what it is) REAR wheel drive 1/10th buggy. It will not have nearly the same good handling, it will be more of a challenge to drive, especially on dusty surfaces, be CONSIDERABLY less durable, and generally less versatile as its significantly smaller than a 1/8th. No doubt you could get the Evader up and running much cheaper (it only needs 1 2s battery for starters), but the 2 vehicles are not comparable at all, the LX is many times more car.

There are many cheaper ways to get up and running, but I think you'd be doing yourself an injustice not to get yourself at least a 1/8th buggy or truggy, they are so far apart from all the other classes in terms of driveability, power, handling, and durability, that its hard to recommend anything else to someone who has the budget to play with the big boys. And don't get me wrong, that LX is still a very cheap car, a real bargain. I have two 1/8ths, a SC8e short course and an Xray truggy (my pride and joy), both of those cost over 500 just for the chassis, and have another $500 of equipment in them. The servos I use cost $110 each for example. Even with the LX you are at the low end of the 1/8th spectrum, but the LX has very few compromises to make that budget (OFNA's power, they have always cheaped out in the right areas in order not to sacrifice durability or compromise the platform, strong plastic, strong drivetrain, but few bells and whistles, which is fine, you cna add those yourself slowly).

What I'm trying to say is that further economy over the LX is probably false economy.
