For the last year or so I have been assembling my first lab/bench. A few months ago I decided it was time to get a good power supply. To date I have collected six of the damn things, all used off ebay. I think that well built name brand PS's are a good thing to acquire second hand if you shop carefully. They hold up well and are a very good value. Including shipping I have paid no more than $75 and as little as $30, though I was very close to buying a nice Agilent for about $130, but I passed and still wish I had bought it. With the bankruptcy of the ITT schools there has been a lot of decent equipment around, though it is drying up. The GW Instek 3020's are plentiful for about $50+ shipping (US$). The BK 1651 is a mid-range unit with 2 variable + a fixed 5V and no fan. These have been going for about $30 + ship. I also picked up three of the older HP 6216A's for $40 or so ea. They are a really nice little single output 0-25V 500 ma unit, very small and they stack nicely. Two make a great + & - supply for op-amp circuit development. It does take time though, and maybe a little working on, but service manuals and schematics for all of these are available free or cheap. One of the BK 1651's showed up with a wonky B channel, but after a good bit of study I replaced a zener diode for 20 cents and it is up and running and I learned a bunch. I think this is a great way to get some quality bench supply's for not a lot of money. Sorry, this got longer than I had intended.
