There's a 20 inch flat panel refurb monitor on sale on apple.com for $499, compared to the new price of $1299. Most of the refurb stuff for sale doesn't have a discount that's anywhere near deep. I'm tempted to buy it, but, is there something really wrong with Apple refurb monitors? I know you always take a chance buying refurb, but if there's some problem that's a given with these (dead pixels, etc.), that others are aware of, I'd love to hear it. Thanks for any advice.
