Upgrade from 450D

[Phoen1x]

I am thinking of upgrading and am wondering what is a sensible increment without breaking the bank? Body only shouldn't be a problem as long as it is Canon. I wouldn't want to spend more than a few hundred quid but would like to see an uplift in image quality.

Uses are mainly architectural and landscape with a little bit of street, so I am mainly interested in detail.

Ta!

What lenses are you currently using? You're probably going to see more benefit from better lenses over a body

At the moment only the kit lens and a nifty fifty 1.8. I got the 450 cheap a few years ago and presumed that a newer body was the way forward.

Any advice for a good lens within the £200 range then, perhaps to replace the kit 18-55?
