we're in the same boat friend. i got an m-6 (thats wat its called, made by chinese i'm sure). got it off e-bay for $89 w/ shipping i think $105 to my door(rated @650cfm). very powerful fan! i blow through 2 600w's and through the wall. those duct boosts are only good enough to add a few pounds to ur hvac system in ur house. they are designed to boost air to long runs of hvac venting in ur house. like a bedroom farthest from your furnace. they are usually used in conjunction with a ductstat. they are a fan, but are not your solution poster. also gypsy, htg is a great source, that 4" is commonly called the m-4. i think you showed him exactly wat he needs!Funny...
just as suggested... did you see the drawing?
The exception being the 2 shitty axial fans... I say it's better to put one at each end... thinking of loss of cfm and disregarding fan life, as this is a temprary solution... he is already looking for a real fan...
