Try and habitat for Humanity Restore in your area. Also did you look in Craiglist?
You can also search under "architectural salvage" in your local directories.
I have been luck y finding them at flea markets.
Try Craigslist if there is an area listed close to you
Thanks for the answers, but I'm still hoping for more ideas.
Garage sales!!! I have also luckedout at flea markets!! Some "antique stores actually sell them sometimes as case lots. the habitat stores are also a good luck choice and very reasonablle..
check out any place that is getting up dated, I have "taken" many of them off home owners who were more than thrilled that I would take them for free!! My last score was 6, in perfect condition! GL
