Depends on how much current you're trying to measure. You can get digital panel meters for as little as $15-20. They max out at about 20A though. These are nothing more than a voltmeter w/built-in shunt.

I figured the people that build the power supplies get the meters somewhere.

Most of them are simply a voltmeter that measure across a resistor, or other calibrated location, somewhere on the internal circuit board.
I got a great deal on a 16v, 10A CC power supply ($35), but the voltmeter did not move freely, it was sticky. The manufacturer wanted $60 for a replacement! For that I could get a good DMM.
