I went for the digital version of the Coleman Mach off e-Bay. Definitely not the cheapest option - but it was black like the analog, no batteries required, and the wiring, including the 2 speed fan operation is an exact match.
Now none of those advantages are huge, so can you get pretty much any digital thermostat from a home improvement store and make it work for 1/3 the price. You may have to pick one fan speed, but we typically only use low anyway. Plus, if you wanted a programmable model you could go that route.
Not matter which one you pick, you won't regret replacing that lousy analog t-stat.
