Oh dear. The weakness of my will is only to apparent.
I couldn't resist this diddy scope for £36+shipping - my second (and probably last) thing made by Sinclair/Thurlby.
Let's hope the trace still works when it arrives.
To me, that thing smells like a junction tester looking for a place to happen.

Non Linear Systems mini scope here. (No, not interested) eBay auction: #174964350030
Ugggh. Did you see the heinous Vert and Time selector abortions on that thing? Only thing it really is good for is to run in X/Y mode.
But not a pig in a poke for US$170 to me in the GWN.
Hell, I'd probably think twice aboot it for $20 at a hamfest.

It's "horses for courses!"
Many years ago, a workmate had a very small portable 'scope similar to that one or the Sinclair.
It was a great help when we were chasing up a 50Hz Mains noise problem on the video cables between the Link Hut & the main Transmitter building at my then job.
Lugging the 7000 series Tek up & down the stairs & into the undercroft would have "got old" pretty quickly.
In a later job, tracing & checking video cabling up on the catwalk above "Studio 1" at the TV Studio I worked at would have been much easier with such a small 'scope.
As it was, we did it "back to front" by carrying a portable pattern generator with us & plugging various cables into a monitor in the control room.
Of course, the cables "coulda, shoulda, woulda" had nice permanent markings, but in the words of the song "You can't always get what you want!"
