Recommendation for Cyclocross Bike for Winter Road Riding?

I am a road rider, but the roads in the area I usually ride in (upstate NY) are full of sand and salt at this time of year, so I don't want to ride my usual road bike. So, I'm looking for a second bike, most likely a cyclocross bike, that I can use to get 25 or 30 miles in on winter days and not worry so much about grit and salt. Any suggestions?
