I finally purchased this machine after trying two other models; the Breadman TR555 and 2200C. My parents have had thier Zojirushi S-15 for almost 10 years with no problems and flawless bread. Desiring to enter the bread machine market with limited funds, I decided to try the Breadman TR555. It consistently burned the bread and revealed a "tougher" center. The 2200C was the biggest disappointment of all. Seeing all of the reviews for this machine as comparable to the ZO X20, I found myself with the ONLY two loaves of bread that were simply "duds" (did not rise properly and crust settings were useless) I had ever had out of a machine. Finally, I decided that Zojirushis could simply NOT be topped. I was right. This bread machine has worked wonderfully and reminds me of my parents machine from the early 90's. Mixing is complete and the Preheat function is an absolute MUST for proper ingredient preparation and yeast activity.
