Ofcourse our cars are much more than toys but buying overpriced tools which do have much cheaper alternitives is far from common sense....
If I have the choice of buying a new engine or this setup board then my choice would be the engine because I can race w/o a setup board but I can't w/o an engine.
I have people come and go because this hobby/sport was to expensive, you can only survive with common sense by only spending money on the stuf you do need.
