Hi, I'm looking for a 2013 iMac, and rather than bankrupt myself I'd like to get a refurbished one. Every day I check the Apple store, but there is nothing. Is this just a dry patch, or should I look elsewhere? I'll buy from another refurb seller if it's endorsed by members of this forum. But slightly nervous about buying such an expensive and delicate item on eBay, cause... y'know. Thanks in advance for any help.
