I picked it up. I was only interested because it was 4-channel, but I'm glad it did.
Amazing condition. If a shop sold it to me as new old stock I wouldn't doubt them for a second. No scratches, no grime on any of the knobs etc. I pulled the cover off to get the handle off it (so I could stack it with stuff), and it's amazingly pristine. It's got fan cooling and even the fan and air inlets don't have any dust on them. My conclusion is it's practically never been used. It's got US gov stickers on the back, so I'm guessing it just sat around in storage for most of its life.
Came with 5 tek probes to, but unfortunately 4 of them are 1x, which significantly reduces their usefulness.
