I do not recall seeing a good set of hole saws on the list. Do not buy the adjustable set, they are normally junk. You will need these for the roll bars, the jack support bars, holes thru interior panels to run your electrical and a bunch more.
Also, a good set of wire strippers/crimpers are a must for the wiring. A good supply of tie wraps for bundling the wires and all the plastic loom to protect the wires.
One of the best air tools I purchased was the little reciprocating saw (like a mini sawsall), great for making cuts in fiberglass.
Don't forget one of those great "Manly" tool boxes from Sears to hold all these great tools you will buy. The bigger the better, you will always be adding tools to it.
ps. I never in my wildest dreams thought I would spend the amount of money on the tools that I did.
But, now I have a great "Manly" tool box filled with tools and Sears can continue to stay open.
Good Luck.
