Looks good but they talk about long it takes to do the wiring. The Gtech just plugs into the cigarette lighter and sticks on the window. One switch on the front does it all (at least on the non-pro meter).
You can get the non-pro meter for $139.95 from Summit Racing

I have the older one and really like it but it has no PC hook-up for graphs.
The nice thing is that it plugs into any car instantly. It will really shut someone up who thinks they have a 10 second machine.
Only be careful with the 60 to 0 tests. We ripped the brake pad out of my friend’s car with a massive stop and good traction, was fun.
