Have you looked at the Planet X Kaffenback or Uncle John ?
The former is steel, but light for it and fantastic to ride. Takes rack and mudguards, I ride it with 35mm Schwalbe Marathon Plus tyres, but with 35s the mudguards are too tight a fit so I use crud catchers and a seat post mounted rear guard. Love the bike though.
The Uncle John is an aluminium framed cyclocross bike, bit more ground clearance. Both good bikes and well under the £1000 depending on spec. The weight difference was only 300 gms so I went for the Kaffenback. Big fan of Planet X though.
