Some good suggestions here but, for me, it would have to be the Deauville, if only for its shaft drive.
However, have you considered a cheap diesel car? When I was faced with a 130 mile round trip for commuting, I bought a diesel Corsa which, at 55-60 mpg and £30 VED was pretty cheap to run and much more comfortable than any two wheeler in the winter, especially on the motorway. When you factor in servicing and tyre costs, it's as cheap as most bikes. Obviously, parking may be a problem that rules this out and it won't allow filtering, but having also commuted on the bike, I found that the difference on a longer journey wasn't a great advantage.
