This is on craigslist near me...asking $55. The person found it in Grandma's house when cleaning it out. They can't tell me whether it works or not...there is no footpedal...perhaps its a model with the knee control?. Apparently there are no legs on the box, "it just transforms out of the box". I'm thinking $55 is a bit steep for a machine that can't be tested to see if it works...opinions?
