well it's a matter of opinion but i feel wizbang (better known as wiz'co) dominator 9000 is a good model.. although if you need to save some money the 5200 is almost as good at roughly half the cost.
if you dont need one larger then 21 inch you can always go with a streamline 21xx series model.
of course i think wiz'co has the best quality a lot of people would say widget electronics inc or WEI has the best bang for your buck.
their flash 50 series is known for high dependability, although stay away from their model-K's, they dont make'em anymore but their known for problems.
