I have a Bernina activa 130 (5 years old). DH bought it for me the Christmas before we were officially engaged. Mom calls it my "engagement ring."
Before that, I used a cheapie Singer "featherweight" (the little plastic ones they made in the early 90's), which was a royal pain after a few years' use. And most shops refused to service it because it was pretty much all plastic parts.
I still have it, haven't wanted to part with it for whatever reason. It was really nice to be able to sew in my room at college etc., and a really kind graduation gift.
I also own a Babylock serger. I've no idea what number or etc. -- I haven't had it out of the box in six years I think!
I ought to take a serging class (I have a good book on sergers too) -- I used it quite a bit for a couple years but really liked to swap between it and the sewing machine, and when there's only room for one to be set up, and it takes so long to set the serger up and the tension is so easily messed up --- I just use the Bernina instead.
With a little "helper" watching and trying to adjust things on the sewing table too, I'm pretty sure the serger is staying in its box for awhile longer.
I am OH so happy with the Bernina. It's one of their lower-end models, but it's all mechanical parts (one of the reasons I chose it, after my fiasco with the Singer) -- I don't need a lot of decorative stitches or anything, I've used it for some smaller quilting projects as well as MUCH MUCH sewing, and never had a problem (other than finding needles for it, because the nearest Bernina shop is a couple hours' drive from here - I've stocked up on them, needless to say). When DH suggested buying it for me for Christmas, I told him that from all I'd heard of Berninas, this machine should hold me for at least 20 years -- he said, when you break the cost down that way, it's a pretty cheap investment for all the work and enjoyment you'll get out of it!
See why I married him?
I also have a 1910 Singer Treadle sewing machine in working condition, a gift from my great-aunt.
It was really hard for her to say goodbye to it, but she knows it'll get used here. I learned to sew on a treadle, and now my children will do the same.
My biggest problem with my machines is where to STORE them ... right now, the serger ahd Singer are boxed up in the (currently just for guests) upstairs bedroom, the treadle is (gasp!) in the garage, and my sewing station is a table right in front of the front door, across from the changing table. Not a lot of room to spread out or leave anything set up for too terribly long (beyond the machine which is always out with current project next to it anyway
). Some day, I want a true sewing room, all organized and cozy and ready to go. But that's a long time from now, and this works. At least I'm not having to clear my machine off the kitchen table for mealtimes!
