right now im using a griddle but the temperatures are very inconsistent looking for the cheapest way to get something thats more controlled as with the griddle im getting temps from 90-130 and would prefer a solid temperature with a +- 5F instead of 40F , i tried searching and found some threads with heat mats and such but im not to sure what i need to get if someone could point me in the right direction looking to buy off ebay so direct links would help me out huge thanks
