Being an Olympus person, I recommend the Olympus C4040 or the Olympus C4000. They both can be purchased for less than $500 on the web. Go to www.dealtime.com
for prices and vendor reviews. Both cameras are 4.1 megapixel, have both point and shoot or manual controls. They can have additional lens and filters attached. They produce great pics. The other cameras mentioned are great cameras also, but I am an Olympus fan. Read Steve's reviews and look at the sample pics.
