Zach,
Definately save your money for the 17-55. It’s a much better lense optically and mechanically then the 18-whatever G kit lens.
As for the Nikon bodies, the D3 is still just a rumor and with the way Nikon is, it could be a year or more until they release it.
Is there any paticular reason you’re looking at the D2x? Honestly, for the type of work you do, the D200 would be much better. The D2x is much heavier and other then the frames per second, you really aren’t gaining anything image quality wise. And you can buy two or three D200’s for the same price.
If you decide that the D2x is what you’re definately going to buy, look to Sportsshooter.com or Fred Miranda’s website to buy a used body. I would definately recommend not buying high end digital from ebay.
Honestly, if I was going to dump a bunch of cash on new gear right now, I’d buy a Canon 5D and a pair of zooms. With all the wide angle photography you shoot, the full frame 5D would be perfect and it looks that Nikon may never make a full frame digital camera.
Just my 2 cents.
BTW I’ll be going to the PhotoPro Expo in NYC on Nov. 4 and will treat you all to the latest and greatest info from the major camera companies. If anyone has a special request, something you’d like info on, IM or email me.
