Oops! Didn't notice the price differential. The Saris is the most expensive of all the racks mentioned.
Still, compared to many other bike-hauling systems we looked at the Saris was actually pretty reasonable. It's very sturdy. It easily handles our two touring bikes (relatively very heavy bikes) as well as a third bike when necessary. The bikes are totally secure and we've had no complaints.
I think I'd be a little leary hauling our bikes on a cheaply-made rack. Is there any place you can go to actually see some of your choices in person? An in-person comparison would be very helpful, I should think. After all, as is true so often, to a large extent you do get what you pay for.
Good luck!

of us, no not one, is perfect; and were we to love none who had
imperfections, this world would be a desert for our love.
