I bought a top from TopsOnLine a couple of years ago for another car. It was a 2-day job, with plenty of breaks and goofing off, not a lot of hard labor, but a lot of fiddling. I'm going to do another one in a month or so. If you're not into spending time tweaking and fine-tuning, it might not be for you. The Mustang top is stapled in two pieces to the last bow, which makes it relatively easy as such things go, but there's a reason why pros charge big money; it takes a lot of time. A complete top kit from TopsOnLine is about $400, as I recall, including heated rear glass, new tack strips, padding, etc. Mostly, you need patience and a really good stapler. I use an air stapler and SS staples because there're about a million staples, all with rust potential.
