Nikon D3000 for concerts?

Someone is selling their Nikon D3000 for 400 dollars which includes the body kit lens 18-55mm, camera strap, rubber eye cap, cable, instructions, and cd manual. It's supposedly a little less than a year old.
I've posted a few questions regarding several cameras that are able to perform well in concerts that take place at night outdoors. Of course, I want to know if the Nikon D3000 is able to zoom in and capture the objects with good quality.
Is this a good deal and would it be ideal for concerts?
Should I just stick with my Canon PowerShot SD1400?

When they say "strap, rubber eye cap, cable, instructions, and cd manual" that tells me it's a grey market package from China on Ebay. Don't get it. It's far too sketchy.

The D3000 is not worth 600$ either, the lens that come with it, is a basic lens, not good for concert you'll need something like a 50mm 1.8, 85mm 1.8 to get something decent, otherwise you'll end up with noisy result due to the high iso and small aperture F4, 5.

Many concerts will not allowyou in with a DSLR camera - they are seen as pro cameras.

Yes you should stick to your long zoom and good picture quality even at night point-and-shoot camera. There's no way you could make a dSLR compete in those criteria. No way at all.
