I have one I'd be interested in selling. It was basically a dumpster find, so it's a bit banged up and missing parts (minor stuff like a bracket and some screws), but it does work. I even replaced the lithium battery pack so there's no need to worry about that. I'd be willing to sell it along with its 5151 monitor, but since it seems like you're in New York and I'm in Southern California, that might be cost prohibitive.
