The article is from 2007 and edited in 2008. I did my research last year for a new sewing machine and it seems that there have been more changes in the industry since then. As just a couple of examples, the Pfaffs and Vikings aren't quite as venerated anymore. It seems the consensus is that the quality has gone down for both brands. The Babylock brand has a lot of bang for your buck, being that it is so feature rich compared to other brands. Naturally, that makes people love them. Juki is now a serious player and shouldn't be disregarded altogether.
In full disclosure, I bought a Pfaff Ambition 1.0 and it is super finicky. I have serious tension issues. I have taken it in so many times for repairs. The technician finally admitted this last time that this is just not a machine meant for quilting. It was intended for sewing. So I have learned the hard way that your search has to go beyond brands, and testing out machines, to finding machines that work well for quilting. It complicates things immeasurably. Especially, if you are a newbie and have never sewn before.
