How much could I sell my Nikon D3000 for?

I got it a little over a year ago from Samy's camera. I bought the kit with the 18-55mm lens and 55-200mm lens. I have the manual and the software disk still. Also the receipt. I purchased it for $758 and it comes with a bag too. The camera itself has a little scratch on the screen but other than that it looks brand new. How much would all this sell for?

I've been looking at a few cameras and would like to start photography. I like taking photos of places, landscape and mostly focused on photos etc; I don't know much about DSLR cameras but I've found a few which I think are good, are cameras better for megapixels?
Could you please tell me which camera would be best for me, out of these please.
- PANASONIC DMC-G2KEB-K
- Canon EOS 1100D
- Nikon D3100
- PENTAX PENTAX KR
- Fujifilm FinePix HS20
- Sony A33
They are cameras that I've seen on websites.
I'm looking for a camera around £200-£400 so if you have ideas please tell me, but I would like a good DSLR camera that can focus on a certain thing, eg- a flower and blur the background. I've seen photos like that where the background is all grainy and ones where it is like smudged and I prefer the smudged ones, so a camera that does that with a 18-55mm lens.thanks
(UK cameras please)
