Update
I ended up going with the Refurbished 2010 27" 2.93Ghz i7 and am thrilled with it. Ultimately I decided that I'd get more use out of the processor and graphics card than SATA3 or Thunderbolt on the 2011 model and that I didn't really have anything specific I wanted with the $100 giftcard. My new iMac arrived a couple days ago and is in flawless condition and doesn't have any yellowing on the screen like some have mentioned. In fact, I'd say it was brand new/never sold except it came with a surprise hard drive upgrade from what Apple listed, so someone must have configured it to 2TB then returned it.
