<<Disclaimer: Verify this information before applying it to your situation.>> Kristine, I've been checking out bread machines also. Consumer Reports just did a review of several brands including the Zojirushi and Welbilt (their December issue). The phone number for Welbilt was listed in the article. It is 800-807-7772. The Welbilt model they reviewed in the magazine was the ABM4100T. It seems that I keep reading about the model 150 on this mailing list. I don't know anything about the differences in their various models but I guess the folks at Welbilt could help you with that. I have to call them myself.
