We use a bridge camera so that way we can keep weigh light and compact. We bought a Panasonic Lumix FZ200, it takes great low light pictures since it has a constant 2.8 aperture and has a 600mm 24x zoom. While the pictures of course aren't going to be as great as a DSLR, for $350 it does a magnificent job.
Here's the spec sheet from
Amazon and an example image gallery in different light situations. Including, low, natural, and artificial light, and it's only a little over 1 pound.
