I've had mine about a year and a half and I LOVE it. It's been a great machine. I'm going to have to part with it for maintenance and I feel like a junkie going into rehab. I've had no problems with it, except that the stitch regulator wasn't working right. It was covered under the warranty. That was a bit of a hassle, but it was the dealer's fault, not Bernina's. Be sure to buy from a reputable dealer unless you don't care about your warranty.
Eventually, I decided to add the embroidery module and I found one on eBay for half price. I really like that too, but it's hard to learn without having access to classes. If you decide to do that at some point in time, first figure out how you're going to learn to use it. It isn't the sort of thing you can teach yourself. Mine had me in tears until I found a class. Now my embroidery module and I are great friends.
