Oomis, first off refuah sheleimah for your knees and your hands and anything else that is aching you.
I have a Bosch – the older model, which I think is terrific. I have a friend who has had one for probably 30 years and she still fixes it and it’s great. I think the best features are that there is the cover which keeps the stuff from spraying out, which the kitchen aid does not have since it mixes from the top. It does have a spill guard or something like that, but cannot prevent stuff from really flying out, which sometimes does happen by me.
The metal bowl is a must for large batches of challah, like on YT, especially with R”H being 3 days this year again and you guys in chutz la’aretz have 3-day YTs with Sukkos and Simchas Torah also.
The nice thing about the Bosch also is that it has many attachments that you can buy separately later on, like a meat grinder, which is good for making chopped liver and even grinding your own meat rather than paying extra for it, like we do over here in EY. I think they also have a food processor attachment for making salads. Mine came with a blender from the start, not sure if the new model does also.
Hope you can save up for a Bosch soon. Nothing like fresh home-baked challah on Shabbos. My kids are not mevater on it NEVER.
Again, Refuah Sheleimah. All the best
