Rare Snuffles?

I have always wondered which snuffles are really rare, and would like to find out what other snuffles collectors are thinking?

This is a link to a collector's opinion:

I personally think, that maybe some handmade Snuffles are rare, and the 25th anniversary 20 inch Snuffles may be pretty rare? Has it been produced in limited production? I do not know for sure.
