I found a "gently played with" Samantha doll on ebay for a reasonable price. She has arrived and is really a nice doll. She doesn't stand alone so could use a re-stringing, but I have too many irons in the fire to attempt that now. I still have a few doll stands from my earlier days doing doll repair, so they will work for now.
I also found a doll on ebay that was advertised as a "Real American 18" Girl". Please note - this is NOT an American Girl doll. It isn't even a good quality knock off. I realize that I was wrong to think that this was an American Girl doll, but the posting was written specifically to mislead people. She is a pretty little blonde and I should be able to use her for sizing some clothes. I suspect she will be used in the toybox at Grandma and Grandpa's house. :-(
