I have a new headliner that needs to be installed, so I called around to a couple local upholstery shops to get quotes. One guy quoted me 6 hrs @ $60/hr, and another shop quoted me $175 flat.

Common sense says go with the $175 guy, but is there anything particularly unique about this job that he might be missing? I can understand a 20-30% price difference between shops, but not a 100% difference...

How much have others paid for this job?
