If I am going to buy another machine just for FMQ, I want to make sure it is very good for the task. I'm wondering if it has a vertical bobbin, as I've read that the horizontal ones aren't very good for what I want to do (hence part of the trouble with the 401). Does "very close tolerances" mean that I will be fighting with it a lot? Does anyone have any experience FMQ on one of these machines? Powerful and fast sounds great, but is that something I necessarily want for FMQ?
