This has been going down to $ 480 often and is back down on Newegg now.
I believe currently on sale at Best Buy as well as S2716DG-R.

For some like myself Newegg may be no tax so this is should be a good deal.

Side note in my case with Newegg storecredit, $ 499 and under is 6 months, $ 500+ is 12 months financing. I tossed in a Cooler Master 212 EVO for $ 30, which also has a $ 10 rebate.
