We bought a Hitichi in 1992, used it for many years. We then bought a breadman and used it, it was good, but when the 2-paddle Zo's came out we upgraded to that. Later on we bought a Zo mini, and it is THE BEST one we have ever had. It is almost foolproof. We have had almost no failures with it.
The big zo with 2 paddles is an old one, and is somewhat picky about things, so I always take a peek in to see how the loaf is being needed so I can add a few drops of water or flour. I think the newer models require less "supervision!" LOL!!!
We make bread, pizza dough, roll dough, cookie dough, and even have baked little cakes in ours. I highly recomment Zojirushi!
