I'm burning through batteries like nobody's business and think it's high time I purchased a power supply. I know I can make my own board with voltage regulators for common voltages like 3.3, 5, 12, etc, but I think I'd rather have something that's adjustable and can source a lot of current in case I ever need it. I've been looking at power supplies on ebay and stumbled across a very low price one that seems to be pretty popular (the seller has sold 159 of them): http://www.ebay.com/itm/Precision-Lab-PS305D-Variable-30V-5A-DC-Power-Suppl= y-/120716204084?pt=3DLH_DefaultDomain_0&hash=3Ditem1c1b3f1834 I've never heard of the brand before. What do you think, good buy or not?
