I think ebay is nice. As long as its still under warranty there shouldnt be an issue. I got mine back in spring for $1600 with rebates and bing cashback (defunct). There's also vendors that sell through amazon for good prices. If you don't mind having the last gen, here is the same model I got for about the same price, without having to wait for the rebates!
Edit: Link Removed. Sold out. But it was a good price...
