Oh! of course.. another great value for money lens and as you say cheaper too.

But it's really limited starting @ 55mm.

if you had to get only one lens due to budget constraints, the 18-105 offers a lot more 'everyday' usability than the 55-200 does.
(but your point was happily accepted.. my bad was not using the correct context)

If I had the choice between a single 18-200(@ $800) or the drudgery of swapping lenses, I'd take the drudgery any day.. 18-105 plus 55-200 make for a better alternative(even for travel) I think.
