We recently rented a large inflatable water slide for my daughter's
birthday party.  They are all the rage right now.  While I was setting
it up I took a good look at the blower that inflates it.  It seemed to
me that these would be just the ticket for a large organ.  They are
fairly quiet, rated for continuous duty, and put out a lot of air.

Has anyone tried one of these?  They are often available used on eBay
because the water slides often get punctured.  There seems to be one
major outlet online for new ones.   It is called B-air.  Their web site
contains specifications for each blower: http://bair.reachlocal.com/
