Just happen to check the Sunpentown web site and found that there's a new model SO-2002 that has a new Nano carbon fiber heating element. I emailed them and this response came back "Hello Edward, Thank you for your interest in our products. The SO-2002 is not available yet, but should be here in about a week or so. The heating element is made of a nano carbon fiber. That translates to a better heat penetration effect and quicker heating time." The one thing I haven't like about the heating element in the turbo ovens was the slow reaction time and am hopeful this will be an improvement.
