I would look for an 06 or newer Duramax. The 06 gained a 6 speed transmission. In 07 the body was updated. Then in 08 - 2010 DPF was added which didn't really cause a lot of issues or hurt the fuel economy that much. In '11 DEF was added which I think is a plus over the 08-2010.I think the exhaust brake was added on 2011 as well.
