Aftermarket Sunroof, What would be the best way? Options

[Cutrara]

I'd really like to have a sunroof in my car. But of course, it would have to be installed by a qualified installer and have a leak-free guarentee. Does anyone here have an aftermarket sunroof? What kind (pop-up, sliding, etc.) How much did it cost?

Here are some things I've thought I'd like:
-Qualified Installer/Leak-free guarentee (of course)
-Can't be the kind that slides into the headliner (I can't afford to lose headroom)
-Pop-up would probably be the best route for me, but I'd get the kind that slides up on top the roof if I could get it for the right price.
-Are there any aftermarket sunroofs like the 3000GT sunroof? It is basically the whole size of the roof and just tilts when its on the car, or you can take it out and store it in the trunk.

Thanks for the help!

the guy that will be making my t-top knows people that are in california that do custom glass and gaskets. he says that they are nationally know and are one of the people that do custom auto glass. other than that you will still need a good installer, but really, all you will probably need is the best body-worker you know of to do the work. like what valo says...get a good gasket and have other gaskets on hand because after market sunroofs/t-tops/targa tops will not be like stock ones.
