Grant's on Broad St. would be someone to check with, also. They've been around a while and have done it all. They did a LeBaron top for me years ago and it came out fine. Like Zen said, it's not cheap because to do it right you've got to replace all 3 layers and that's as much labor as doing 3 tops!
On the other hand, I did the top on a Ghia myself a few years ago and thought it came out really well. If you're patient, methodical, mechanically inclined and have a dry place to keep the car for a few weeks of off-and-on work it can be done. Get instruction books and videos and study them well before doing anything. I figured the gamble was worth the thousand-dollars-plus I'd be saving. No shop will ever care as much about your car as you!
