I have a DB Sorrento currently, and I love it. Got it on sale for $249 from Sports Authority 2 years ago. Its got SRAM x3 shifters and RD, Shimano tourney FD, and shimano rear freewheel.
It was a heck of a bike for the price, heavy and durable feeling. Swapped out the knobbies for road tires and its good to go on and off road, as long as its not *too* off roady.
