I Post Em As I See Em
But will keep my eyes peeled for the models you are looking for, and if they do pop up on fleaBay, will give you the heads up.
Ebay has an automatic message notice for members that tells them when a item they are interested in is listed. IIRC it is under "saved searches". One simply selects to be notified if say "Maytag" or "Maytag ****" is listed. eBay sends you an email when anything corresponding to your search is listed.
Try also looking on Craigslist for your area and if willing to travel, several surrounding states. Final suggestion is to hit those estate sales.
Best of luck,
