Just get the one I linked. Trust me. When it comes to something as useful as a bench power supply, you don't want to buy the cheapest piece of shit you can find. It WILL break down.
Those cheap chinese supplies are cheap for a reason. I bought one a few years ago and boy do I regret it. It can't regulate worth a damn in current-mode. It died a few months in - fixed a loose cable. Died a few weeks later - fixed a bad comparator. Died a few weeks later - shorted pass transistors due to heat sink overheating. I had to replace the pass transistors and add a bunch of heat sinking to make it somewhat usable again. It's still on my bench and I use it for some things where I don't care about the regulation.
ALSO, do NOT trust ebay test leads. No one checks them, but they're 28 awg or smaller (so they can save 6 cents on copper!) which means they're useless for anything but a voltmeter or for low current. Learn to make your own test leads - get banana plugs, alligator clips or mini grabbers, and solder them yourself using a more respectable 18-16awg. Lamp cord is perfect for that.
