See the threads below. I’m not aware of anything much changing over the past few years. The last one talks about making bread.
I got a Dr. Goods one, five years back; I think it cost around $8,000? Haven’t regretted it. If you’ve got some kind of pizza stone or other heat sink, it’s fine for bread.
I dimly recall looking at Japanese ones in the department stores and being horrified by how much more expensive they are - plus they had added costs, like possibly redecorating the kitchen to fit the oven. I think on Forumosa I’ve mostly read about the Dr. Goods or the Costco Kaiser.
