docopp (Ed) & other Blasto-Dry Users,I had the same dilemma a year ago...I looked into the several major blowers available.
My impression is Air Shammees are built ok, but Blasto-dry are built better for the same cost.
I installed 5 Blasto-drys in my 5 self serve bays about 6 months ago, their use is increasing.
I am glad I put them in, they are very very well built, zero problems so far.
Customers like them and compliment us for having them.
Mike Doyle and his brother own the company and you deal directly with Mike.
A straight up guy to deal with.
(I have no interest in their company, and I was a normal full price paying customer)
