I agree, "... just what have I created" in regards to my own DH! He is constantly online looking for vintage machines, and every other day we go to whatever Thrift and Goodwill stores we happen to drive by.
Just tonight he sent me 8 pics of various old machines, wanting my opinion on nothing more than the price they were listed for. He is more into collecting them now than I am! For the moment, I am content with my "New Automatic" treadle and the "Domestic" from the 60s I have. LoL
