If you're still on the hunt for a 4311 I found two authorized online retailers selling below ~$1,300 (before shipping). Vanns and Onecall. I went to Onecall first and asked for their best price. Was quoted $1,320 delivered. I later called Vanns and they would match. I ended up ordering with Onecall since they quoted me first. Good luck in your search.
