In which case you will have a zillion suggestions for a zillion reasons. Have a look at
this one. Way below your budget, but with as many bells and whistles as you need. Not many can outdo this model for macro (close-up) and zoom. Coupled with image stabilisation, it makes for teriffic all round package IMHO.
Sure, there are many many others, but this would make a decent
benchmark if nothing else until you know exactly what you need from the camera.
Also, have a look at the other manufacturers (click manufacturer on the left, then click on 'camera').
Just my 2 doubloons worth.
