I'm thinking about upgrading my sewing machine.
I have a very nice Simplicity SA2200 Creative Spirit Plus 45-Stitch which I bought a few years ago. It has a nice heavy metal frame (more important than you know to avoid a skittering machine when sewing) and all the stitches you really need, including a buttonhole function.
But I have my eye on the beauty pictured: Singer's CG-590. It is touted as a commercial grade machine although reviews I have read are chalking this up to marketing rather than fact. A few things about it appeal to me. It seems to be a bit more "mechanical" and by that I mean you can fuss abit more with things like needle position. Also, someone, whose designs and workmanship I really admire, uses one. Barring user error, it can only be a good thing to emulate her choice ... or so I am rationalizing it. And, I really dig its no nonsense machine aesthetic. No curvy, white plastic here!
This is going to require a blitz of financing though (i.e., knitting)!
UPDATE: I love it. It runs much more smoothly than the last one I had and has just enough adjustment and stitch variety.
I've been doing loads of machine appliqué with it and some sewing for Baby. I am very happy with it.
