I'm watching this on Amazon Warehouse Deals to see how far it drops....
Amazon.com: Pentax K-30 Weather-Sealed 16 MP CMOS Digital SLR (black): PENTAX: Warehouse Deals
I bought the second last one at $623 on the 19th, yesterday it was at $611, now down to $589. While only the photos show the 50-200mm lens (it's not in the description), the model number (15646) matches the pictured bundle. Also, with Amazon's 30-day return policy, you can't go wrong.
If you Google around, the 'Like new' cameras people have received have ranged from having a slightly dented (but never opened) box, to getting a camera with <100 actuations.
