I replaced a Coleman Mach analog with a Honeywell RTH111. It doesn't support 2 fans speeds unless you modify it with an extra switch, but it's only about $22. You can pick either fan speed and go with that. It uses batteries instead of 12VDC power, unlike the Coleman Mach. See attached wiring pic.
Another alternative is a Coleman Mach digital, which is a direct replacement, but it's a bit pricey, about $90 I think.
Others will probably chime in. Almost anything at Home Depot will work. The RTH111 isn't programmable, but for a couple bucks more, there are similar programmable models.
