The D40 will only be available in kit.
Really? At the UK price, that means it will have some serious competition from the "bigger" dSLR's. A 400D is only £40 more expensive.
Just had a look on Jacobs, they don't have a store in Leeds, but there is one in Sheffield and Hull, both of which are close enough to go and have a look at.
I know this is sorta subjective, but how do Pentax/Olympus lenses compare?
