There are various prices. Not all converter boxes are made the same. Some of them have remote controls, some are very basic, and some aren't the same quality as others. This is a wide range; it's a very competitive market out there.
What I can tell you is that the U.K. had speculated that its boxes would be closer to the $100 range when it started. At the end of the program, they became an impulse item at the checkout counter. That's what market force is.
