Ecost.com is taking pre-orders for Panasonic E30K (the black colored one) for $554 + $13 handling fee and no taxes. ETA is July 18th.
I pre-ordered te E30S for $554 and the next day they bumped it up to $583. If you pre-order, you lock in the price, and if it goes down- you can cancel and replace the order. They will not charge your credit card until it ships.

p.s. they have a no return policy (15% restocking fee). Good luck to all
