GPS Camera Detection

What camera is best for this?

I have a Nikon COOLPIX P100 that takes great photos, but doesn’t do that great at concerts. I am looking for a camera that takes clear photos at concerts(ex: Adam Lambert concert) The concerts I go to have lasers and stuff like that and the objects are constantly moving. But I also go to house party concerts(ex: Monte Pittman) where the lighting is odd. I would like for the camera to take pretty good scenery photos too as I like to take nature pictures as well.

What I want:
Would rather a Canon
High ISO
Doesn’t need to be small/compact
Good zoom(My Nikon has 26x zoom & love that about it)
I’d like a fast shutter speed since many objects will be moving
Highest price I’ll go: $475

I don’t mind getting a used camera. I will most likely be buying this camera off of Ebay or Amazon so higher priced cameras will be cheaper if I buy a used one.

I am not worried about accessories because my birthday is in about 3 months, then Christmas is only 1 month after that so I will be getting a lot of money or I can just ask for the accessories. So the price doesn’t include all that kind of stuff.

canon sx230hs with 14x zoom & good lowlight photos for $299. otherwise just get a dslr with a large aperture and zoom lens which will set you back maybe $800. check out the canon s95 and nikon s9100/s8100 too
