Nothing works as well as the older conventional type TO ovens, they just don't build them well anymore. halogen bulbs won't hold up, they deteriorate kinda fast, and a little expensive to replace. The under $100 bucks TOs for what we use them for will take em out over a short time. I have looked at the heating elements on the newer stuff very cheap compared to the heavy duty older ones. I guess keep the price up and cut quality with light duty parts is the model for profit. Don't wast your money on most of the new stuff out there wont cut it for the demands that we use them for
