Yeah, several places (via Pricegrabber.com) are showing it for just under $700.
To the OP, if you want weather sealing, then the DA*16-50 plus DA*50-135 is a very nice set. However, it's big and expensive. The new kit lens pair (18-55/50-200) are weather resistant and not that much money. That would definitely be a cheaper option, and if the IQ is the same as the older (non-WR) versions, then they would be good bargains. Plus, they're smaller and lighter, so should travel a little better.
If you're willing to give up WR, the 18-250 is a really good travel lens and generally gives you the same IQ as the kit lens pair. I use it as my vacation lens and I've never felt constrained by it.
