And I finally have the last missing piece to finish my equipment needs - just won an Agilent E3610A power supply. Was listed at $85 plus shipping, I offered $75 and they took it. Comes from a test and calibration supplier (though they aren't calibrating it at this price - they do offer to calibrate it but did not supply a price for the service), and is guaranteed to be tested and working. Also they mention their packing methods - so I don't think there is much risk in having damage from shipping. Another plus, it comes from NJ (and I am in the eastern half of PA). This unit will suffice for now for my generally low current low voltage projects, though I'm sure in the future I'll want something a bit more high power, and maybe programmable (just because).
