I bought one on eBay recently....can't say I got a bargain but it's a good little machine.
On shipping, ask that any seller pad the tip of the thread spindle well if it's coming in a case. My seller didn't and the tip of the thread spindle poked a hole in the top of the carrying case. There's only 1/4 inch clearance between the tip of the spindle and the case. DH fixed it and I'm okay with that.
To be sure I don't have a problem again, DH (he's so clever) made a little cap for the spindle...took an small wooden spool and glued a small square of 1/4 inch wood on top. Perfect fit and he even painted it black!
Good luck finding your machine!
