Just saw the video. Not impressed. I fall into the camp of those who think the front panel display and control pad stinks. The update speed on the output voltage indication is what I would expect of a $50 piece of junk. What were Rigol thinking ?
Sorry, in my book a total fail.
I recently purchased three GWInstek PSP-603 programmable power supplies. They may not have the spec of the Rigol but at GBP80 ($120) each they were great value. I can use them independently in a neat vertical stack or as separate units around the lab. Up to 60V at 3.5A output, so pretty versatile. The lower voltage PSP-405 was also available. That had greater voltage resolution. Mine were Brand New Old boxed Stock from a company that was being shut down and selling off its inventory. The PSP-xxx series have a more friendly user interface and a nice large display. The KISS principal has been applied well.

And finally, what's with Rigol trying to make their kit look like it came off the Starship Enterprise ? Don't get me wrong, I am a Trekkie, but I need a power supply that is quick and easy to use. I thought the days of trying to impress with flashy displays and lit buttons died in the 1980's ? I remember Alan Sugar (AMSTRAD) having lots of flashy lights put on his AV equipment to sell it to those who were impressed by 'technology' Basically bragging rights but the kit was still a pile of cheap junk behind the flashy front panel.
Just one hint from my side to people currently in the market for a new PSU: don't overlook the Siglent SPD3303 series. There are some pros as well as some cons comparing it to the Rigol, chances are you'll like it better.
I refuse to even consider an electronics product, where you have to register just to download the user manual. They couldn't even bother to tell on their homepage whether it has linear or switching regulators.
I remain confident that if Dave opened up a Rigol product that reeked of oversight, bad design, or dangerous flaws, he'd have a field day showing them in all their glory and ask the manufacturer to respond.

...Anything I've missed?
- That Korad PSU he managed to blow. (Result: Hmm, did Trio Smartcal stop carrying the item?)

One thing I noticed: Don't most supplies have the Black (Negative) connector on the left and the Red (Positive) connector on the right?

Yeah I noticed that one too.
That said my ITT/Metrix AX322 also has the positive terminals to the left of the negative.
Slightly of topic, speaking of standards

the best is Xantrex/Sorensen/Ametek, no need to think what is on right on left ^^
The risk of blowing an expensive IC or test board is one reason I still prefer, for lab work, all manual switches and no programmability.
I still prefer 3 single output supplies for redundancy and reliability; if one output dies, I still have the other two whereas a 3 in 1, the whole supply is taken out for repair should one supply go even if the other 2 are working, or worse a single output failure could take out all outputs.
+1 That $420.00 for the Rigol would buy 4 or 5 PD precisions including shipping. Yeah there are a lot of features you are not getting on the PD's but I still love them. Wait a minute.... I am preaching to the choir
When you find someone who won't ask for $200 to ship one of those to Romania (or any country in Europe) let me know.
Robrenz, in USA maybe, not anywhere in the world, lucky you

Just in case it wasn't obvious, the benefit of the higher resolution is in the ability to increase/decrease the voltage/current by 1mV/1mA intervals, and not just the readout showing an extra digit. This can be very useful for doing things like measuring the small-signal gain of transistors etc.

Sorry I was not trying to make anyone feel bad. As messed up as many aspects of the US are, it certainly has many more benefits.
