Thermostats are really pricey to get for just one snake... and if you are using a commercial heat pad and not flexwatt you really don't need it. A dimmer would be adequate for a single pet snake IMO. Air conditioned houses aren't going to get too hot for a snake without a thermostat unless the heat pad takes up the whole cage, in which case you have bigger issues. That's why our store doesn't sell flexwatt or thermostats, because we cater greatly towards these kinds of customers with just a few snakes who don't have rack systems or designated snake rooms.
