I feel like I'm going in circles trying to work out what type of protection I need for various setups at home. There aren't many power outages where I am, but I am convinced that the house (a rental) has particularly poor wiring. So, I want something that will "clean" the line running to my valuables. I'd be very grateful if the MR community could offer some advice! Setup #1: Macbook Pro (C2D 2.53), often connected to power source, attached to Dell U2410. Dual tray JBOD external HD (70W), Brother DCP 7020, Airport Base Station (wireless n), cable modem. Setup #2: iMac (2007), Seagate external HD (250GB?), some other little gizmos (obviously not my personal setup ). Typically, people looking at UPS' are Mac Pro users but, as I say, I am concerned about the power here. Thanks!
