Go with the Dive-Rite Transpac II. It can be found at LP for $350 and is a great alternative between the traditional jacket style BCs and the popular backplate/wing setup.
The Transpac is extremely modular and should you want to try a backplate, just connect a plate ($100) to your harness and make it a "Transplate", while keeping all you BC accessories (weight pockets, wings, clips, etc.). If you need more lift (i.e. for doubles) get a larger wing. No need to get a new BC altogether.
It is the best of both worlds and relatively inexpensive.
