I have the Quik Rack ("Mach2" technically), and it's great. The cost exceeds the entire combined cost of bikes I've ever purchased over my lifetime.
But it takes the friction to go out to ride to zero. I don't even leave it on my car, but can affix it within 2 minutes, including the time to walk it out to my car. It works seamlessly and simply. It addresses all of the issues with the 1up, and, having seen the 1up driving by, looks better too.
Is it worth it? It depends on if it's worth it to you to have something you don't have to worry about, that does its job without hassle, complications, or adornment. I can't emphasize enough how super-cheap I am, and would never spend on bikes what some people do, but I felt the Quik Rack was entirely worth it.
