Show your favorite and most used benchtop PSU

Ok, some DP832 v1.09 PSU hacking porn, LOL!
Before:
After a very long fangled routine to update the bugger:
(Realistically I will never need any of the options other than the accuracy upgrade. I might try the LAN for a bit of fun as I believe it has a webserver available!)
And proof that the accuracy upgrade works, once you "turn it off and on again", that extra digit! I think it's great for circuits that only consume milli-watts. Check it out:
I'm a happy bunny! :-+ :-+ :-+

Those are mine:
HP6111A - My preferred. Just dial the voltage and that's it. Stability is a plus.
PS503A - Second. Very compact and there's the modularity of the frame.
PM2811 - I think I overdid here. Don't really need it, but got a good deal. Sometime in the near future I'll play with the GPIB on it.
Rolo:
As a first post I like to show my bench PSU, it's a Delta Elektronika E030-3. This is a Dutch brand, famous for the quality of their powersupply's. It's old but works perfect.
It delivers 0 to 30 volts up to 3 Amps. Originaly it came with an analog meter that had to be switched to Volts or Amps. Not very practical so I made a digital meter based on an Arduino and a ASC712 current sensor board.

I have a pair of Tektronix PS503 power supplies and they have become my favorites. I really like the dual tracking floating outputs.
If I were to design a kit power supply, I would duplicate their feature set although not their exact design.
I am including a photograph I took from when I changed their input capacitors.

@ David Hess
Thank you for showing your favorite set up.
Could you elaborate the interesting things(at least to me) in the pictures?
1) Why two wire connection instead of one from the input cap? Is it factory default or you modified it?
2) What those two resistors do between Lo and Hi terminal of DM502? Why two Rs instead of one?
3) What is the purpose of the caps on the second DM502?
Thank you in advance.
