Nikon professional camera or polaroid z2300/z340?

I need a camera cause mine is broken. I need good quality photos, a good battery and it needs to be practical as I will need this for many trips. I like the polaroids idea of printing but I'm scared to get one and the quality of photos would be bad. I have heard that nikon is a really good camera. If nikon, please tell me which model. There's also a price difference so please help!

Nikon professional cameras start at $4000 - without a lens.

Polaroids are junk, but if you want a camera, work out a budget and talk to a dealer. There are other brands than Nikon.
