I DuraCoated two -82s, and if someone will do a quality job for $100, I say jump on it unless you're the type who likes do do stuff yourself.
There's a lot of prep work required to make it come out right. I did mine as a "project," so wasn't concerned about the time. Investing in the DuraCoat and airbrush, etc, came out well over $100. If you don't want to go thru the time and trouble--send it off!
