Good point. If you're going to be using different sized flexwatt (11" and 3" for example), then you will need two separate controls for each. Or if you ever want to house multiple species with different heating requirements, you'll need separate controls for the heat.

If this is your plan, then I would bite the bullet and get the Herpstat Pro. It's awesome. It will control 4 seperate heating elements. I have mine hooked up to control the corn snake racks, ball racks, cornsnake incubator and ball incubator - all with one unit.

But if you know that you'll only be using an identical rack with the same size heating element throughout then you'll be fine with any of the ones you listed, but I'd personally recommend the Herpstat (not the pro, just the regular one).
