Not always easy to know what traditional Amish will go for. It needs to be old fashioned, but not TOO old fashioned. One of the early advocates of immunizations was the old Puritan, Cotton Mather. Pretty sure his era is at least contemporary with, if not predating, the more modern Amish technology.
The Amish at the market in my neighborhood use plenty of modern technology, at least at work. And they come down from Lancaster County in ten-passenger vans. Apparently, at least the more “modern” ones are allowed to ride in cars, but not drive them.
I must say, they have some good looking women.
