Thanks for the help guys... I'm leaning towards the 18-105 just because I've never been a heavy zoom user and the 18-200 adds $500 to the package. Seems like all the lenses have similar performance though with regard to distortion. Also, how annoying is the zoom creep on the 18-200? It seems to me like it would be nuissance if shooting flowers or something. It's not like I can really miss a shot by not having more zoom... I'll just get it at lower resolution, right?
