Sniggler,
Here is the best advice I can give on buying a DB. Before you go and plunk down a wad of bills on a boat, go out and look at every drift boat you can. Talk to as many boat owners as you can. Check out all the availble options for boats. Dont be oo concerned on what make of boat you wont to buy. For the most part aluminum boats are pretty much the same. Just stay away from RB and Hyde. Willie, Koffler, Fish Rite and Alumaweld are all good bets. Diamond Back is another make I would reccomend checking into.
When you do purchase your boat get 9'6" oars, They are by far the best length for a 16' x 54" boat.
