hetkind's post (a few posts back) is correct! ...You are budgeting too little and trying to get an underpowered compressor in comparison to the job requirements you mentioned.
I have a relative who has been both building and selling compressors since 1966 and I asked an expert at that company...
In case this helps with your decision, my father-in-law owns a company that sells Wayne Replacement Parts. (and many other hard-to-find replacement parts for air compressors). I hope this helps with your situation!
