Also lenses ... What I'd like (and I suppose wouldn't we all...) is a general purpose zoom in the 35mm equivalent of 28 - 100 with reasonably good optics, with most of the use probably being at the wider end.
Total budget is around £1,600 and I have to try to include a 1gb memory card in that as well.
Basing judgments largely on lens options makes a lot of sense to me: at similar prices, lens options seem to vary far more than the performance of DSLR bodies themselves.
If you have Nikon lenses at longer focal lengths that you would like to keep in use, it would seem mostly to be a matter of choosing between DX mount options. If you would like the speed of the 17-55 f/2.8 DX but not the price, there are some third party options that might be worth looking at, like the newly announced Tamron 17-50 f/2.8
http://www.tamron.co.jp/en/news/release_2006/news0215.htmland a Sigma 17-50/2.8 that has been around for a while.
Those third party lenses also fill a speed gap for Canon EF-S mount bodies, where Canon's own standard zooms limit you to f/4-5.6 (but with stabilization in the 17-85).
One possible downside to all these "17-55" type lenses is that no-one yet offers a comparably good and fast telephoto zoom that carries on from 50 or 55mm: the choices so far are either slow entry level f/4.5-6 zooms, or ones that start at 70mm.
My personal favorite "digital format standard zoom lens" is none of the above: the Olympus 14-54 f/2.8-3.5 in 4/3 format, which is a 25-100mm FOV equivalent for me, because I mostly use print shapes like 8"x10" and 8 1/2"x11" and for those, the "4/3 to 35mm format factor" is 1.8x, not 2x. And there is a nice 50-200 f/2.8-3.5 telephoto zoom to go with it. However, if you seek performance like more than 3fps or more than 8MP, Olympus offers nothing yet.
Given your interest in the wide angle end of the standard zoom, do your needs go wider too, and if so, have you compared options like the 12-24mm f/4 DX and Canon 10-22mm f/3.5-4.5? (Or even the Olympus 11-22mm f/2.8-3.5?)
