how much are you willing to spend? also, are there are specially technologies you want in a bag? did you want something a bit more heavy duty?
I am actually in the market for a new bag too, and I have been checking out whats out there. if I had a choice, I would prob go with a Bag Boy with the "Clip-Lok" system. Here is an example

Clip-Lok bags are cool because they keep your clubs in place and in good condition (no rattling). It is hard to see in the pic, but there are notches for your shafts to lock into place. besides that, I think bag boy makes pretty tough bags.
