David, thanks for sharing your experience. Which one did you get?
The link I sent is all one link, looks like it got broken up in transit.

Subject: Re: [TCML] Reliable 20VDC 10A Variable Switching Supply?
The links you provided seemed to either have expired or are broken, but I
happened to have gotten one of those variable 30 volt, 10 amp, Chinese made
power supply units for Christmas (my daughter was asking me what I wanted
for Christmas, so I figured why not that) ;-) Anyway, it is over current
protected so you can't pull much over 10 amps, even with the leads dead
shorted. There's pretty fine voltage control from 0 all the way to 30 volts
and the ripple is only a few millivolts. May not be suitable for a
professional lab environment, but at ~$80, including free shipping ($0 for
me, since it was a gift), it's certainly good enough for my purposes ;-)
