EnderWiggen, perhaps your wife really doesn't want to quilt and is using the fancy expensive machine as an excuse to get out of doing it.
Have a heart to heart talk with her about that. If she truly wants to quilt, then she will settle for a less expensive machine and do it. Otherwise, it's just something she thinks about with a bit of longing, but doesn't really want to do.
If she decides she really wants to quilt, she can get a good Brother machine at Walmart for around $200 that has lots of stitches and attachments and a slightly larger throat than the usual 4" on most domestic machines. I recently bought one and it sews wonderfully.
It is, by the way, my 3rd Brother. First one lasted 6 years and then was dropped on it's head while in transit between home and vacation and back - definitely not a fault of the machine. I replaced it with a Brother SE350, that I do love - enough bells and whistles for me, plus, if I ever decide to try embroidery, I can.
There are many good options for quilters these days. We don't need the 'best' machine made, we need the 'best' machine we can afford.
