Heathkit IO-102, I ran out of functional scopes a while ago and this was $20 (complete with the build manual!) and down the road, 5 MHz single channel is good enough for most of what I'm into anyway. Mostly works, builder did a semi acceptable job, acts like the HV and maybe lower rails are low (haven't measured yet) but all the bigger carbon comp resistors on the power board and in the HV divider have drifted up 50+%, so that and a couple electrolytics should put it right. Came with graticle, I just pulled it off for cleaning.

The biggest issue with it besides bandwidth is that it is not triggered. I ended up blowing the entire vertical amp with a brief contact to a flyback lead.
Would 'complete system' include the satellites?

Sure! Just pick one of your choice

I bought a Keithley DMM6500 which arrived yesterday. An amazing piece of equipment.

Most disappointing tool but have since found a use for - mini board preheater:

Link for the welder?

A Logitech K400 Plus keyboard with integrated touchpad instead of a numeric keypad:
Mainly, I'm interested to see if I can speed up zooming/panning in Inkscape, Gimp, EasyEDA, KiCad, by using my own Linux userspace daemon that grabs the touchpad, and produces customized events and controls instead of mouse movement when in "tool mode". I use a mouse to control the pointer, but my working style in these is such that I zoom and pan very often, and I'd rather use my left hand to do that (separately from my mouse control).
Alas, I'm right-handed, and keep my mouse on the right side of the keyboard, so the touch pad is really on the wrong side for me. But the fact that this keyboard is narrower than full-sized keyboards, helps.
If it does not work out, I can always donate it to a family member who has a media center but no wireless keyboard for it.
(This was inspired by Simon's Programmable keyboard topic, although my use case is obviously different. I initially described the idea in this post.)
