No, not silly at all!
I have a permanent eBay search for my favorite bear. Ok, well, I still have the old bear, which was meant as an upgrade to my old stuffed dog.... I am attached to them because they feel a certain way. I have searched SO many different shops to find just the right one, to no avail.
Maybe you won't be able to find the exact same doll, but could you find one that comes close?
