one thing to consider doing ---i always meant to but just never got around to it -- is to build a small compressor shed (a 60 gallon vertical doesn't take up much space.) attached to the outside wall of the garage and hardline the airlines to the inside with multiple drop drains s and driers. It's the way we set up my brother's collision repair shop. a 20-30 gallon compressor doesn't have that great of a volume to cfm rating to support much hardcore sanding/grinding use without it constantly running down. They're ok for impact & air wrenches and filling tires, but not much more. A 60 gallon will give you a fair amount of run time before cycling and can support the tool ok for a couple minutes while cycling. I've gotten about 12 years so far out of mine, sears 230V upright.
