We just got the VMania windows about two weeks ago. Got the twin sliders, one on each side, and they are great (don't need the door poppers with these). Jon B told me to take down the rear window, and it is amazing how much ventillation you can get in the car. Leave it up, and with the windows in place, you can actually hear your stereo without turning it up all the time. It's actually fairly quiet inside. Northwind also makes slider windows and they are very nice too, however, visibility is a bit more limited. Still, not like the factory side curtains, as they really restrict your view. Both companies offer a considerable discount to VCA members, so check them both out on the internet, their sites are avaialable through links here on the VCA site. I believe either set of windows will work with the factory hard top. They also give the car a very different look again, it's like - Look Ma, I've got windows!
