I expect you'll see many of them for sale at the end of ARRA.
I have a used blower door for sale. It's a Minneapolis Blower door, about 3 years old. Everything is in great shape and it comes with a padded case for the blower fan. I bought it for my auditing business but now work for a non-profit so it's no longer needed. Please contact me at cameron at cloudcityconservation dot org to discuss.
oops, this is from 2011, never mind.
If anyone else is still interested though . . . .
