AZ,
I use a Fujifilm Finepix S9000 which is little more than a glorified point and shoot. The real key(s) to getting good shots is lighting, using a tripod, using the macro feature on your camera, and avoiding a composition which incorporates the two extremes of exposure (black on a white background). The latter can be accomplished if ones knows how to control exposure. I have yet to learn how to do that so I stay away from it. The other thing is to take some shots and then check the results, if they aren't satisfactory then try again. Within the pictures that I have posted here it is pretty easy to tell which were taken before I learned some of these lesson fully.
Thanks for the compliments.
