So the main difference between a "basher grade" and "race grade" design are that basher grades are older and extremely less durable, but the classes are fairly universal between a basher and a racer.
The kit I recommended above (401R-T) would be the same class as the Traxxas Rustler 4WD, but the 401R-T offers far more tuning options, will be easier to work on and will be far more durable and easier to drive.
Note that the kit doesn't include any electronics, but here's what I would recommend to install in the 401R-T to help keep costs reasonable:
$75 - Motor/ESC Combo with 5800KV motor (recommend a 20T pinion with this motor)
$40 - 2S Shorty Battery
$11 - Basic charger
$39 - High Torque Servo
$55 - Computer radio with telemetry, gyro and loaded with features
Total - $220 for electronics
*** Most RTR's come with piss poor electronics that need to be replaced anyway, so you're saving yourself the hassle/expense by getting decent quality electronics on the first go around
Other expenses will be tires, paint, tools, etc
