Looks like the decision has been made, but I thought I'd post in case anyone else is looking. I already had a Yakima rack on my VW Golf, so I just bought a bike rack for that. Works well and VW makes it really easy to install the Yakima system (nubbins already on the car that the towers hook right into).
I like the Saris racks, though (had never seen them before). It would certainly alleviate my paranoia about driving into the garage with my bike on top of the car..
