The 18-55 sells ok on the used market, as does the 55-200. Makes the changeover to an 18-200 not so bad . But I know the feeling of pain about the lens prices. I bought an oldschool push-pull 80-200/2.8 last week, time for some sweet portraits (and pre-focussed bike stuff. It focusses painfully slow - even more so if you don't use the 4 focus limit positions and let it rack the entire range). I couldn't justify $1.5k for a used 70-200VR ($2k new) or $3k for a new 70-200VRII.
