I need some RAM for my mom's 800 Mhz G4 iMac, and the cheapest price I've found is at Powerlinememory.com. They have 256 MB for $56 and 512 MB for $98. This is cheaper than Crucial and OWC. Has anyone ever bought from Powerlinememory? I'm wondering if they're reputable. I've had good experiences with OWC before, and everyone says Crucial is good. I'd like to save a few bucks of course, but not if it means having a bad online purchase experience.
