[time-nuts] power supplies

[jimlux]

What with telework, I'm doing more timenuts-ey stuff at home, and the 
power supply conundrum has come up.

There's a plethora of interesting widgets scattered across my bench 
requiring variously, 5V, 8V, 12V, and 15V.

I've got a box full of various fixed voltage supplies, mostly linear, 
picked up over the years.
I suppose I can package a bunch of those up in a bigger box with banana 
jacks or binding posts.


And then there's some things where you'd like current limiting and/or 
variable voltage.

So I've started looking at inexpensive bench power supplies - there 
appear to be dozens, if not hundreds, of these available.  There must be 
dozens that are all very similar - They're switchers for the most part, 
displays, etc. for $50-100, from different vendors, all similar.

Are they essentially commodity? Or are there particular brands that are 
good or bad?

Are they all noisy?

Weird UI problems (7 menu layers with a single knob)?
