No info on the company but I prefer racks that hold the bike by the tires, not the frame.

It depends on your budget and how much you expect to use it. I googled that rack and it looks like a couple of others, such as Sport Rack and one sold by Performance. I own a 4 bike rack similar to that one...I don't need it often (I put my bike in the bed of my truck unless I'm taking others) and to me it didn't warrant paying twice as much. With my level of use I've had no problem wearing the paint (yet!). I would, however, suggest making sure that the sliding part that holds the bike uses a ratcheting action rather than a knob to tighten it. Mine has the knob and can loosen during the course of a drive. Also, before buying make sure your vehicle can handle a 4 bike rack; my wife's car won't. 

All that said, the more expensive ones are more expensive for a reason. They're better. Whether it's worth it depends on you.

Thanks for the info.  I drive a 3/4 ton truck, so 4 bikes on the hitch is no problem.  I would only be using the rack when the family rides, which isn't often, when it is just me the bike goes in the bed of the truck.
