While the new mirrorless cameras are out (Sony Alpha) not much has changed. Low light is a problem area and once in a while a new person to this flames everyone that such a camera is not made for cheap.
Look again at the prior discussions and find one that was mentioned.

I came across an older thread from 2010 with some great advice on some cameras that were affordable (used anyway) that performed well in low light but since 4 years have passed I thought I might ask the question again as I'm attending a concert in about a month and will be 6th row. I'd like to have something that will fit in my pocket and perform well in low light. In the past I think the low light has been a real issue.
