I'm cutting back on my arsenal, and have decided to let my trusty 350 go. It is completely stock with the exception of an extension for the headphone jack. The headphones plug into the rear of the cuff now, and the wire is inside the handle, so it doesn't tangle. The unit is in perfect condition, and looks new with the exception of a couple of scuffs on the bottom of the coil. I do have the original box with the machine as well. I'll let it go for $225 shipped anywhere in the lower 48 via UPS ground service.
