I've been looking for a jointer for awhile now. I've missed out on a few 6" jointers but from what I've read the 8" is better to have anyway. I found an 8" Rockwell 37-315 Jointer with made in Pittsburgh stamp with a serial number from it looks like around 1980. The jointer looks to be in decent shape from the pictures. The asking price is $500 and I wanted to get some feedback. Price seems high for the age but new 8" jointers run 1k+ easy. Any thoughts or concerns I should have.
