What's wrong with the DP832?
It's Chinese alright but Rigol seems like a solid company from what I read around.
I also have no problems with what I've bought so far.
I have that PS and it works just fine. In at least one way it is more user friendly than the Siglent equivalent in that there is a keypad for numeric entry instead of just spinning a knob. It has a knob for minor twiddling.
I also have the DS1054Z scope and it also works very well.
When you look at PSUs with current limiting, read the manual to see how it is adjusted. The Rigol, and most higher quality PSUs, will have a digital adjustment that is set with the voltage off. The cheap supplies expect you to short the output and turn a pot. Not my favorite way of setting things.
There has always been Chinese bashing on this forum. Some warranted, some not. And, yes, an HP supply would be nice as long as it had equivalent features for a lower price. It won't... There are lots of supplies with analog meters and they're cheap enough, I suppose, but they aren't what a modern PSU should be. That's why they're sold as surplus.

ETA: So, I watched the video only to discover that I use about 1% of what the PS can do.
