With cameras you get what you pay for. save the extra $ and get your self an slr with a decent macro lens... you can get a used slr body and lense at a decent camera shop (not walmart, japan camera or your parking lot photostop) like henrys (
www.henrys.com )
I don't know what's availible down there, but in any decent city you should have a bunch of camera shops.
Photography is one place where having the right tools helps with the quality.
