Hello. I was looking to buy a DC power supply that I could use to power laptops, and other miscellaneous DC powered items I run across. Unfortunately I'm not up to speed on the latest, greatest, or best buys in electronic equipment.
I really don't care how new or old it is. If it has digital or analog controls...rackmount, benchmount, etc. I think 48V is about the top end of what I'd use, and maybe 10 amps?
The Keithley 2260B-80-27 Bench Power Supply (http://www.keithley.com/products/dcac/highspeedpower/360_720/?mn=2260B-80-27) looks really nice but is super pricey.
Ebay has a 60V 5amp that's kinda low on the amperage, but it's cheap... (http://r.ebay.com/PiOnf2)
I'm open to advice, even if it's that I should have posted this in the beginners forum. ;D

No opinions, recommendations or options? I've thought about building one, perhaps out of a salvaged PC power supply but they're not really designed for variable voltage.

You might want to keep your eyes open for the HP/Agilent E3000-series (don't remember which model fits your V/A requirements, but some go to as much as 20A). Of course, if you're willing to fix it, you can get "for parts/repair" units cheaper that "tested" ones.
Lots of us like the aesthetics of the Power Designs supplies. The bench models go up to as much as 60V, but top out at around 5A (e.g., PD6050).
Of course, some supplies support two or more devices hooked up in serial or parallel operation with one acting as the master. So you could opt for that to get more voltage or more current (and more flexibility as a result).
