Really I need a camera for travel, so I would like somthing easy to carry around. But I really want to be able to take pictures of my tank... all these macro pictues got me hooked. I am a poor college student so I got to keep the price down.. under $300 for now. What do you pros recommend for an intrested beginer? Dont laugh to hard but would a canon sd630 do anything cool. I want to be able to show some creativity.
