What is wrong with the bernina you have? Is it a computer machine or a mechanical?
I love my 15-91.... i am glad that has already been mentioned. If i had to buy new or higher end used a mechanical bernina would be my choice. I am sorry the dealer annoyed you. Can you just call them and ask about the availibillity of a new/used mechanical bernina? Over the phone, the dealer will have much less info to work with an no "captive audience". I doubt the upsell would be atempted, but if it is you just repeat your question.
