WoW!! You've gotten lots of different people loving lots of different machines. And there lies the problem. We all love our machines because we are all different. You need to find the machine that works for YOU!! Shop around. Sew on lots of machines. Decide what you really want to do with YOUR machine. Do you want embroidery? or just a straight pretty seam that will hold well? I have vintage machines as well as a fancy Viking that does all the fancy stitches. I quilt mostly on the vintage machines. They are all metal (a very important feature) and sew such a beautiful stitch. I taught sewing in public schools for over 30 years and found the 'new' machines were mostly junk..... at least the ones with plastic parts, etc. They didn't withstand the use they got and I was always working on them to keep them sewing.
So, go out with your list of what you want the machine to do and then try lots of different ones. Good luck.
