Jet, I think that is just beyond what I want to do, I'd like portable. Also, my brain says tires will reduce vibration passed to to the floor/house.

Just keep your expectations in line if you go with something like that. 5.3 scfm and a 30 gallon tank will probably limit you to 2 minutes of use with a die grinder at a time. I have a little harbor freight 5 gallon I use for being portable and it was like $75. Easy to throw in the truck, etc. Might be an option to go with a bigger one and a really portable one.
