Thanks for the input guys! I found a used Swagman 4 bike rack for only $100 so I think I am going to go with that. Here it is: http://www.amazon.com/Swagman-Cross-...6105949&sr=1-1
Seems like most people with the platform bike racks on here are very happy with them.
PBM317- do you ever get rubbing issues with the Thule cradles? Paint damage seemed to be the most common complaint with the traditional style of rack.
