Score!  That's an $800 supply!

At 30V and 5Amps, it will be a work bench work horse.  Plus it has a=20
knob.  Digital programmable supplies are fine - for lab fixtures,=20
production work, etc. but with no knob, they suck for engineering work.=20
Yours has the best of both.

Yes, you could build your own and learn a lot.  You could learn that=20
there is more to building a nice supply than you think.  Having a nice=20
supply and getting on with fun tinkering work is a lot more fun.

In my book there are three pieces of test equipment you want done right:
a) power supply
b) DVM
c) oscilloscope

You should have lots of fun with your new supply.
