Yakima and Thule are reliable, well-made brands. I have a thule roof rack for my kayaks and haven't ever had a problem. My friends and I share a yakima trunk mounted 3-bike rack. I think it in part depends on what you want to spend. For something around $100, you do get a bike rack that lifts your bikes sufficiently away from the ground (depending on your bike's geometry, you may still have to remove a tire in order to keep it clear of the exhaust pipe) and will hold 2 or more bikes and is sturdy. We chose ours because my friend has a wagon and I have a sedan and we can use this type of rack on either car.
Sierra trading has a rack for a good price. This must be an older model, so I can't directly compare it to mine. If you will just be carrying one bike, there is a 2 bike model on sierra as well.
