i would highly recommend the Nikon Coolpix 5200. The coolpix's have always been known for their impressive macro ability. I just bought this camera for a local real estate office, and everyone there finds it easy to useas well. You can find it online for around 280 at a few places (

Heres a review for you (

If thats a little too close to your budget i would recommend the Nikon COolpix 4100, which has just as good of a macro ability but for only about 200 dollars. (

If you have any further questions just ask!
