I agree with others that stated a good dealer is IMPORTANT when buying a new machine. I would suggest that you spend some time looking at the different machines, and when you go to the store, take along some fabric and thread, like you would use in sewing at home, and see how each of the machines behave with what YOU will be sewing on. Most good dealers should let you spend some time sewing on which ever machines you are interested in.
Each machine has it's good and bad points. And each sewer/quilter has their likes and dislikes. So while it may be helpful to get others opinions, they may not have the same requirements as you do.
I wouldn't make this decision quickly, take your time, visit the dealers, more than once if necessary. Go look at any machines that has a dealer within the distance you are willing to travel for service and classes. You want to be happy with which ever machine you choose, and not regret your decision, about the machine or the dealer. (By going back to the same dealer more than once, you can see if they are friendly and helpful each time, or if it was just a random occurance). The last thing you would want, after investing in a good machine, is to have lousy service from your dealer, and not be able to get answers to questions, or help with using the machine once you get it home.
I have a Pfaff, and love the IDT, and couldn't live with out it. One of the reasons I went with a Pfaff over another brand, is the dealer. I didn't like the way I was treated by the Viking dealer when I was looking for a machine, but the Pfaff dealer took all the time I needed to explain all the features of the machine, before I bought it. (this was a long time ago, before Viking and Pfaff become part of the same parent company). And then gave me classes on how to use the machine. I have never regretted my decision to go with the Pfaff, even though I look at other machines now and then, I just don't like the way I'm treated when I walk into other stores to look at their machines.
