I just saw this on-sale:

0-30V, 0-3A Mini Bench Supply-MPJA, Inc.

0-30v and 3A.

I bought the $60 vertical version:

0-30V, 0-3A Variable Benchtop Power Supply-MPJA, Inc.

I used it for the first time last night. Great little unit! Love being able to directly drive and test diodes this way. Wish I'd known that for $10 more, I could have gotten the 5A unit though.

Nice PSU. The only thing that worries me is (<200mV RMS max ripple). I am shure someone will chime in on the specs.

I don't trust chinese switching PSUs like that with laser diodes. Not unless I see them on a scope first. You might get away with it, but I recommend a linear PSU instead.

I haven't blown a diode... yet. I suppose a $50 diode blown precisely because of a low-cost supply would make a higher-cost supply a no-brainer.
