I do not mean to be a prune but I saw a number of comments about dealer support and have an addition. Another part of dealer support is honesty. We will not go into names and places and war stories but honest dealing between dealer and customer, both directions I imagine, is crucial. And that honest dealing is before and after the sale. Please talk to other sewers in your area and see what they have to say about the dealer(s) they have done business with.
Good luck. I hope you are delighted with your new machine and the place you will be getting it and that pleasure continues far into the future.
