They also have the LRP chassis here

This 'should' be easier to get the spares for than the Reely chassis.
Personally I would look for a second hand TT01, they go for quite cheap (without electrics) and will be tough and you can get spares easily and cheaply. Its also quite acceptable with a slow motor.
