I'm so pleased that we're gathering a nice variety of new sewing machine reviews here at New Zigzaggers and I certainly think that this review format makes it easy to compare brands and models.
But seriously, if you've found this site because you're looking to buy a new sewing machine, you must also check out the reviews at an amazing website, PatternReview.com. If you register, you'll be able to search and read reviews of sewing machines of all ages, makes, and models for free -- the only catch is that you can only access the reviews that have been written over the past six months. Many, many people write reviews at PatternReview.com, however, so you'll still get an unbelievable amount of information.
And then, if you want more, you can upgrade your membership to "Friends of PR" for $30 for the whole year. This is a bargain, people, if you love sewing and do a lot of it -- once you have your machine, the fine seamsters and sewists at PatternReview will make your life many times easier and better by telling you which patterns work and which don't, and offering details about how they made adjustments for fit and function. I rarely tap into the wealth of articles and interviews that are posted on the home page, but I can while away hours gazing at other people's creations and reading the details of how they made their masterpieces.
(In the same vein, I must also mention the brilliant open-source sewing site Burdastyle, where amazing people create amazing clothes -- often with no pattern at all, or from patterns they share with fellow Burdastylers. There's no real sewing-machine component on Burdastyle, but it's a great site for inspiration and community once you get into the process of creating stuff!)
