I feel fortunate for the deal I got from the estate sale of an interior designer. My 401a was in the desk cabinet with the cams and different feet and manual. I love it. Got it cleaned up which didn't need much. Few worn spots on the desk top. My DH used it the next morning to repair a couple spots in a denim jacket. It purred like a cat getting it's belly rubbed. I paid $150.00 and was lucky since lived so close nearby, they delivered. I've seen others priced higher without the cabinet and needing a lot of work. All depends on how bad you want it and the shape it's in. A lot of factors need to be taken into consideration. I look at it as a pay scale $20.00 = needing a lot of work and having to buy a lot of parts to very needed cleaning and lube job to higher what is needed.
