Just a note on getting better photographs.
A great camera never hurts, but if you want to take better pictures of instruments, the first thing you need to work on is improving your lighting. The light quality of electronic flash is great, but if you use an on-camera flash, you often won't get good results. That built-in flash is designed to help get enough light in for details when you're popping off a snapshot of your mom, but when you're shooting your finely polished Alembic, you'll get a lot of glare. At shooting distances, for all intents and purposes, the on-camera flash is at the same location as the lens, so the reflections will all be captured on film.
The simplest thing you can do to improve your shots are to go out to Sears and buy a pair of cheap halogen worklights, probably around $15 each. Place one at your right, 3-4' away, aimed at your instrument. If you take a picture now, the instrument will be well-lit so you can zoom in for close-ups but there won't be any glare as it's being cast off to the left.
The only bad part about using one halogen light like this is that it will cast harsh, dark shadows. So plug in the other light and place it on a similar position on the left. Now the instrument is fully lit from all angles and the left light wipes out the shadows from the right (and vice versa).
Halogen bulbs like this are catagorized as tungsten lamps, so if you're shooting film, you would want indoor film. With a digital camera, you should set white balance appropriately for accurate colors.
You can spend hundreds more on color-controlled photographic spotlights, or thousands on a pro flash system, but if you're not going for artistic effects, this system on the cheap should work fine. With the pro gear, you can control the balance between lights so you can retain some shadow (this is called key and fill lighting), control where the light goes (use shutters so you don't get glare off of a bridge), or diffuse the light source to soften the shadows. But if you want super-sharp details, this is the way to go. Once you've addressed the lighting issues, your $10 point-n-shoot
While you have all this stuff set up, take a picture of your mom too. She'll look better than with the built-in flash too.
