About Nikon D3100 IQ?

First at all my problem is that I can't decide what to buy D5000 or D3100.
I would like to buy D3100 because of the 10min video vs 5min at d5000, autofocus is not important for me, anyway I'm doing it mannualy. D3100 has full HD but even this is not so important for me but the video length. This is the first think

the second one:
I have checked some sites for sample pictures and I have noticed that D3100 make much more blurry photos than D5000. I love D5000 IQ but not D3100. Well because I have enough money just to buy kit I need good quality of the kit lens. 18-55VR works perfect on d5000 but my oppinion is that 18-55VR just doesn't work well on D3100 maybe cause of the extra megapixels. I need your oppinion.

BUT, at one site I saw samples on d3100 18-55 nad they were great so now I can't trust to noone of these sites. Please let me know some sites to check the samples of d3100 or maybe your samples uploaded somewhere but 100% cropped.

If I see that d3100 makes good pictures closer or even better to D5000 I will be very happy because I will find out what will be my next camera.

thanks a lot and sorry for my bad english.

Added (1). I'm asking about the D3100 and 18-55 VR how they works together, I know everything about d3100 specs. I don't know is the samples sharp as d5000 at least

The D3100 is nearly in every way, better than the D5000. The blurriness caused in pictures is the photographer's error, not the camera. The 18-55 works perfectly with the D3100, megapixels has nothing to do with it

get the D3100
