Welcome to the Board!
I have a Janome 350e. the largest hoop is 5inches by 7inches and it also comes with a 4inch by 4inch hoop.
It uses a flash drive to transfer designs from the computer.
It comes with 3 (I think) built in alphabets and a lot of designs.
I think I paid around $1200 new but I'm guessing.
I took it out of the box, set it up and was embroidering within 1/2 hr. It's very easy to use.
Good luck with your search.
