I have a huge air compressor, a Robinair vacuum pump, an engine stand, two jacks, 6 jackstands, 2 ramps, a diesel compression guage but no OBDC II or I scanner.
I consider a very useful tool to be the very high quality adjustable ball joint puller I bought.
I consider my most unique tool to be my Better Halfs hands, which are very small and and have mechanical talent as well and have helped me enormously.
My dumbest tool was the Huge Compressor. I dont use air tools that much because I dont my neighbors to think I am running a "Shop" and the noise is a concern. I could have done with my small one, all I need is the Cleaning Air, even if I am rebuilding an engine. Finally you can never get to a lot of places with huge clunky air tools anyway...
