What is the best small Point and Shoot/DSLR under $500?

Hi guys,

A friend of mine is looking for a new camera (she doesn't have access a community as great as The Verge). She wants it to be small, take good low-light pictures, and be under $500. It doesn't matter if it's a Point and Shoot or DSLR it should just be small as in pocketablish.

Thanks guys!
