Regarding the Ricoh GR Digital; great little camera [I had one, a GR II] but the fixed [non-zoom] 28mm lenses doesn't meet the OP's stated needs.
Also, Ricoh does not officially import or support their cameras in the U.S.
They can only be purchased from Adorama and PopFlashPhoto and any warranty service or support comes from the store itself.
As for the Finepix F200exr it does look promising [though I have yet to see a reputable review] but the ~$400 price tag might be a bit more than the OP was looking for [?]
