You could check out the Buy and Sell section on the TIB forum (This is Blythe).http://thisisblythe.com/
(see the side panel for forum). There are alot of used dolls that sell here. There even some Kenners for sale at times. Beware this site is very addictive.
For those of you that can get to NYC Gina Garan has sales every so often at her studio. I made my sis go there. That is where I got my Minra.
