Thanks, Burnt; I just found out about those respirators on ebay, too. They look like a great deal, considering all the others are much pricier and do essentially the same thing. I'll probably endf up with one of those unless I spring for the Axis Citation combo turbine/respirator unit.
I have to admit that I'm still curious about the hair dryer/hose concept, though.
