I also went with the hitch mounted bike rack. I'd read so many threads about people having problems finding roof racks b/c there aren't many options out there. Furthermore the hitch mounted racks are surprisingly cheaper. I believe mine is a Thule, it's for two bikes and collapses against the rear door when the bikes aren't on it or you just take it out and put it in the garage where it is now. It doesn't weight all that much, just a little bulky due to the size.
