Initial reading up has listed
Genesis croix de fer : Heavy but good looking
Cannondale caadx : Very CX so racy/nimble/flighty/harsh etc
Boardman cx comp : Same as Cannondale
Gt grade : By all acounts a decent bike, looks better in the flesh
Norco threshold : Dunno
Whyte Suffolk : Something about Whyte that turns me off so I've no idea if its any good but they seem popular.
Consider the new Charge Plug (may be over budget), Marin Four Corners, Specialized Sequoia or AWOL, Genesis VAgabond theres loads more really. I'd avoid the ends of the spectrum ie CX or Touring. The gravel bikes are plentiful and would be a better bet IMO.
