Having said "don't specify actual cameras" for anything close to a film SLR in the digital world you are looking at £2000 upwards. If you want a really good digital camera that looks, works and feels like an SLR you can't go far wrong with the Minolta Z1. I am a professional photographer and that is the digital (as opposed to film) camera that I have. There is now a Z2 in the range. click here for the Z1 or here click here for the Z2
Obviously, my preferred film camera is my Hasselblad.
