I've got a 400D and its magic. I think the only other thing I can add is that the new 450D has the 'Live View' feature that allows you to shoot using the LCD screen rather than the eyepiece. Must admit it doesn't bother me not having it.
I'd agree with womble...pay a little extra and get it in the UK. I had to send 2 back before I got one that wasn't faulty.
