I did not buy one of those, but they look really nice for the money. Carpeted inside, sliding windows, 2 piece unit, good choice of options. Looks like the same one at hardtopdepot.com , who is a manufacturer. I researched these last year, never found a bad thing about 'em. I would call the manufacturer to just ask some questions and check their attitude before buying.
I have an 06 LJ also...just picked up a really clean oem top off ebay for $800 in Utah. I'm not hooking up the wiper, spray, or defroster, and I don't have the harness for it anyways.
There are usually some on Craigslist also...be patient and a good deal always comes through.
