OK so I found an original EICO Uni-Probe for sale on eBay but they want $57+ $5 shipping, plus it has a funky 2-pin plug that looks a little bit like the old switchcraft mic jacks but its not (it's one of those old CB/Ham Radio Mic Jack Plugs), so I wonder if its from a little newer VTVM than mine is, or perhaps a kit version of this VTVM?

Is $57 a reasonable price for one of those probes or is that person asking too much?
