I came very near to purchasing a USC. I really liked the way it felt in my hands although I did not get to shoot it. The biggest reason I chose not to buy it was the cost of extra magazines, at $60 a pop it made getting the ten or so I like to have for each of my weapons a bit unreasonable. That may not be an issue for you and perhaps someone else here knows where to get magazines a bit cheaper.
