My "rip-off" tour was around 120 Euro/ night "full board" (incl. 3 meals), all trips, and two guides and a driver. Plus airfare (which was really a rip off on Air Koryo...) I assume that there will be a surcharge for US citizens. Did the tour in 2006, so prices may vary.

Wouldn't really consider this a rip off. Booked thru http://www.nordkorea-info.de/index.htm which is a German site, but there is a english description of the available tours here http://www.nordkorea-info.de/tourism..._rundreise.htm .
You won't have the choice of hotel or anything else. They put you where they want you to stay. The guides are, however, very helpful and try their best to please and show you what you'd like to see.

You could drop this guy an email, he's a German organizing tours of DPRK and very helpful. He might be able to help you as well (email address on the english tour descirption site, all on the bottom).
