I'm too cheap to pop for yet another piece to go with my new Star Sizer so here is my Diy parts list for doing it on the cheap and dirty.
One new heater from Omega and one used thermostat courtesy of my wifes tired old iron. It beats the cost of a new one and should perform in a like manor. The only things left to do are to drill a 1/4'' hole for the heater and wire it up neatly and to scrounge a piece of sheet metal in which to cover everything up nicely. Now, to find the time to complete this.
