Just had the priviledge of dealing with the guys at Auto Racks (autoracks.com - just beside the museum of science and technology) for a roof top rack for my car. I can't say enough about the service and willingness to answer questions, etc. Also, they told me last week about a sale they are having on Yakima roof top boxes starting tomorrow, so I held off buying until then. Great deal, essentially $100 off any box or another $75-$125 off of any Yakima box (so $175-$225 off list price).

This is a great deal if you are looking at getting one of these. They also carry Inno racks now which are a lot less expensive than the Thule or Yakima equivalent.
