If you're painting it the same color, they should charge 25-30% less than Andy's since they wouldn't have to paint door jambs, under hood, etc that is required with a color change. Those are the items that take a lot of time (=$$$) to sand and prep for paint.
My knowledge of MAACO is OLLLD (like me), but based on what I know about them, I would stay away. I don't believe they do much prep work, so 2-3 yrs from now your nice paint will be flaking off. Speed work NEVER equals quality when it comes to body work / paint. Once again, MAACO may have changed but I would be very hesitant to have them do anything.
Not sure I'd recommend going to TJ by yourself or even at all. I'm sure they'd do a decent or good job, but you'd have bigger brass ones than me if you did.
