I currently use a Ranco Thermostat to regulate my melamine rack but really want to get into proportional heating (dimming style). I found that there newest product is affordable and handles a decent amount of wattage. The HerpStat Intro, i do not currently own this thermostat but i really would like to pick one up. Read over the details and see if it is right for you. It surprisingly has a lot of features that the larger units have, with the exception of less wattage.
