KRA that is a nice machine.
HelenAnn I agree. They're trying to sucker in a higher offer than it's really worth. I don't play guessing games like that. Tell me what you want up front and I'll decide if I want to deal with you. I had a nearly identical machine in great running condition that I bought at Goodwill for $25. I've since passed it to a friend of ours.
That W&G is nice but there's no way I could justify the current price of $721.
Here's a Wheeler & Wilson treadle base for a reasonable amount, especially if you need it for parts.
