I have the OEM rack with snowboard attachments. It is one of the easiest installs and removals for a rack. There is just one bolt on each side of the support that screws down into the roof, but will not damage your paint at all.
Sam, if you would like, you can come see the rack in person to check it out... I would highly recommend it if your taking to the slopes (just like I did many times this past season)...
