Thanks for the kind comments!
The other power supply, the switchmode PSP-2010, I took apart when I first got it (in the true spirit on EEVblog I guess...).
The construction quality of this is fairly good again. They seem to have added a sheet of plastic to duct airflow over the choke and power resistor, but outside of that they seem to have got this right first time.
There's a good number of ferrite beads, threadlock on most screws, soldering is neat.

In use, I'm more than happy with the power supply. The controls are digital, which means I can dial in x volts with a limit of y amps. It also has limits which you can set, so that if you are testing a circuit that has a max vcc of 12v, you can cap it there, and not worry about spinning the dial too far. The power limit is also an interesting feature, but I have yet to use it.
RS232 is a good addition. You can both control and monitor the supply using this - the command set is very simple. I'm contemplating adding a cutout and FTDI board so that I can control it with USB. Currently I'm using USB->Serial adapter from about 10 years ago and it's crap.
It's a useful supply for powerful projects - motor controllers, RF amps. Also really useful to use as a charger for different battery types as you can monitor and change the charging profile from a PC - I've not written anything to do this yet as the USB->Serial adapter fails all of the time!
