I would buy it, (but then I have 2 BabyLocks now). I have a Decorator's Choice, but it is older than the one you are looking at. I've had it at least 10 yrs now, and paid around 1,100 (on sale). I bought a smaller BabyLock Grace last year.
I love both machines. I stuck the Decorator's Choice on my bathroom scale, and she came up at 15 lbs. The cover and the foot would probably add another lb to it, so I would say around 16 lbs.
I have not had any problems with either machine, and she travels really well.
