unless you move up to a something better than a p&s, low light focusing is going to be a problem. And it's not much better on a DSLR until you get an add-on flash or something with a focus assist light like on a canon DSLR(canon 300D, 350D, 10D or 20D), but then you're getting into a higher priced set of equipment.
