I picked up a line of Radiant Mats.Ideal Heat.
It is a 1/2 copper band instead of cable, better wattage at lower prices, better mat than any I have seen

We now have the lowest priced Mat in the nation! it runs about $7.33 per foot

We dropped Thermosoft,Suntouch,Warmtile, still carry Nu Heat but they are to expensive.
