The Panasonic GH2 body only is on the down tick again, you can now get it for $680 with free shipping at Amazon by Amazon where it is eligible for the optional and stackable Panasonic Lens Instant Rebates.
As of the time of writing, it is cheaper to buy the GH2 body and the 14-42mm lens through the Instant Rebates ($680 + $123 - $50 = $753) as opposed to buying the standard GH2 w/14-42mm kit on its own ($780).
Also participating in the instant rebates is the 12-35mm f2.8 lens with a current price of $1100, and a combined purchase shopping cart discount of $200. So if you buy one of the participating M43rds cameras, you can add the 12-35mm for +$900.
This round of the Panasonic Lens Instant Rebates is stackable. You can buy one camera with up to four lenses, and get the four individual discounts in the same shopping cart. And if that's not enough, you can do two bundles per household. So if you want to max out or go M43rds crazy, you can get two Panasonic M43rds bodies and eight M43rds Panasonic lenses (choice is limited to the models shown at the aforelinked pages).
This round expires November 3, 2012 (or earlier if sold out; or later if renewed/extended).
