I have been researching this for about a month now. I have read a ton of stuff about all the racks and the biggest thing I have learned is that more you are willing to spend the better rack you are going to get IMHO. Up until about a week ago I was set on buying a Saris T-rax pro rack till I took a really good look at the straps on it in the store and that made me change my mind even tho it is still looks like a good rack. I also posted a question on this forum and another forum and most people were saying look at the Thule rack so I did. I found that the Ridgeline 954 fit my Impala and looked like an awsome rack so I checked it out in the store and liked what I saw. I looked at the hollywood road runner deluxe rack as well online and the rack looks well built but, I just don't like how the base is built with the extra brace and welds. The more weld points you have the more chance of having problems is my personal experience. Other than that the Hollywood racks don't look to bad either just not for me I guess.
At this point also the LBS where we are getting our bikes at is willing to give me a great deal on the Ridgeline also and they didn't steer me to it I told them what I was looking for so that was a plus.
