The 156mm (~6 inches) ZX series looks pretty decent. It claims 1125 lumens per housing for $49.95 per light. That's a pretty big light for my taste though.
Rigid Industries Duallys are a lot smaller and have ~1300 lumens at twice the cost. Rigid lights also have good information about beam pattern on their website and a good reputation.
Oh well. At least there is more competition coming out which will ultimately lower the prices.
