need help upgrading old MEARS thermostats...

Hi Everyone,

I have a 1960s house with electric baseboard and radiant ceiling heat. (Bills are through the roof!). I want to upgrade these vintage MEARS thermostats into something modern, sleek, and most importantly programmable... can anyone help me find a compatible model?

I have two different kinds - the really old ones are:

MEARS model M7A Single Line Break

and the slightly newer ones are

MEARS M602 double pole

Ideally I'd like to replace them both with the same model.

    Honeywell and Aube both make suitable stats.
