sun roof?

hi wondering if anyone has had a sunroof installed, but not by manufactures?
if so how much were the service fees?
about how many hours of labour does it generaly run?
and any other info I guess would be nice, brands of sun roofs and what not like that....

id guess its a 4 hour job for a manual sunroof (opens by hand) and 6 hours for a mechanical job , takes body work and slight modification to the roof for fitting.(roof is thin and bows in if installed wrong)
So im guessing a sunroof install would cost 300+ bucks to intstall. Plus however much it costed.
