Hehehe! That 301A is going to be a very nice deal when it becomes available - and probably the 401A too.
I have to be careful going places like that with my husband. They would have found kindred spirits, and I'd have to drag my husband away. Get him talking about working on older sewing machines, and he's set for hours! (not that I mind, though).
These vintage machines are cheap enough you'll never suffer financial ruin - you'll suffer from lack of room!
