Very happy with the Thule Helium I purchased a year ago.

I think it was cheaper when I bought it, but in any case I think it is a good value due to the built-in locking mechanisms and the light weight. In the negative column, when putting two road bikes in place, it takes a bit of finagling to make them fit suitably to lock them down with the straps. The three bike version might have been worth the extra bucks to save this hassle.
