installing a shop roof vent attic fan

I'm posting this because I decided to add an additional roof or attic heat vent fan to the shop , I called a local roofer to get an estimate on the cost, I was quoted $175 for the ducted roof fan and $550 labor for the instal, look at the links below and you will get a good idea how inflated those cost estimates are

watch the video's
youll ideally want one 1600cfm fan for every 1500 sq feet of floor area as a minimum, but one 1600cfm fan for every 1000 sq feet of area is going to remove heat trapped in any rafter/attic area far more efficiently, the idea here is to constantly vent otherwise trapped ,hot attic air and maintain a constant moving air flow thru the rafters as it tends to keep the rafters dry, and lower cooling costs and make ceiling fans cooling the shop more efficient, and effective

(and ID bet money the fan the contractor has in mind is not this good)

BTW HF has several reciprocating saws,this ones got several good reviews ( at $60 I'm still thinking its not very good quality)

most of the cheaper reciprocating saw versions are total crap and can,t cut butter on a hot day,
Ive had several of the $29 and $39 versions and they are not worth the time to take out of the packaging in my opinion, both of the ones I was given as gifts, stalled easily against any resistance.
