Ordered mine here for $399 with Memorial Day $20 USD discount and $15 Drop rewards balance. Figured it was worth a shot for $364, and $75 Drop rewards earned to spend later. At 'only' $289, it's a $teal. ;-)
Will post updates after arrival.
UPDATE #1: Estimated Ship Date was 13 June; showed 'Reserved for Shipment', as of 17 June.
UPDATE #2: E-mail from Drop received, Subject: Drop Update, confirmed 'unexpected delay', on 17 June.
