I'm almost embarrassed to admit this, but I'm partial to the old HP/Harrison 6200B supplies. They do 0-40 volts at .75A, or 0-20 volts at 1.5A. CC and CV modes, but you have to live with an analog meter. They don't take much space, and there are usually plenty on eBay for around $50. Some of them require a bit of refurb, but they're easy to work on and there's a manual available at the Agilent manual web site. I have three of them (along with a newer Agilent supply with digital readout but similar rating) on a shelf above my workbench, and a couple of spares tucked away. For demanding applications like looking at ultra stable or ultra low noise OCXOs, I use a "super regulator" board that's available from http://www.at-view.co.uk/alwsr.htm in the UK as a bare board, board with low noise op-amp (surface mount) installed, or complete unit. Using the 6200B to drive one of these boards built for 15 or 24 volt output works very nicely.
