Just curious as I'm in the midst of switching to Mac from being a PC guy, I'm trying to get a bead on what would be a good deal. I was considering grabbing a 27" refurb that they have for $1299, or one of the 21.5" refurbs for $1099. But I know a someone who is looking at selling their 24" iMac 2.8ghz with 4mb Ram / 500gig HD for $850. Does that sound like a good deal? Or should I keep my sights set on one the first option?
