Ive been experimenting with building my own tempering machine and the best temperature guru in town is of the opinion that forced air is the better method because it ensures the air circulates which doesnt happen with light bulbs or a heating element.  A solution when using an element or bulbs might be to put a small internal fan into the machine to circulate the heat to prevent 'hot spots'.... hope this helps.
