Photo Radar is another good forum, attached to Digital Camera Mag by Future Publishing.
The Nikon has had favorable reviews over the other entry level camera's and if I was to go for one it would be the Nikon D3100. However you need to go into the shop and hold each one and see which suits you best.
Also this is where manufacturers snare customers, you aren't just buying a camera you are buying into a system, look later down the line because you will get hooked, it's unavoidable, so what might you want to buy later on, flash, extra lens, remote shooting device. Look at costs of these.
I don't think you'll go wrong with the D3100 though. As for price...
