Posing this to owners that have had theirs for awhile. Looking at one and thinking I would need 40 top offs of my 60 min tanks to break even money wise on that compressor. Looking at a good 40 hrs of run time assuming 3k to 4300 top off is about an hour ?? Just curious how many have a good 50 hrs + on theirs ?? Also has anyone rebuilt one ? Was it straightforward and were you able to get parts from target forge ? Thanks guys.
