I have my mom's 'vintage' Husqvarna Viking 6000 SL 6460 'Embroidery Sewing' Machine. It's solid metal and came with the sewing cabinet which was really convenient for storing accessories (cams and such). I've used it for years now, but still have a 'thing' about trying out all the cams for the different stitches! They make me nervous!
In my defense, they used to stick pretty badly and I was scared I jam or break something using them. Then I had it professionally serviced and they seem to move super easy now, and the technician had some nice designs he put on the sample cloth for me showing me how easily they worked now! But I still am a bit 'twitchy'. I am making some diapers for my latest baby, due in November, perhaps I should make some cute border details and just 'get over it!'
I have a 1986? (not quite vintage, but solid metal and a 'workhorse' type machine) Babylock BL4-428 Serger that I got for $100, and it came with a large bag of serging thread and several additional books on serging. It would 'freeze up' after about 15 minutes of serging, but once I had it serviced, it's running like a dream! Made like 30 cloth wipes with the cutest border on them!
Recently bought a Singer Quantumlock (14T967DC) Serger, as it's 5 cones and has extra feet and goodies for doing special stuff. I've only had it a few days and am learning a few new stitches at a time, so as not to overwhelm myself....took a full day to make sure I threaded it right! It handles nice though and I LOVE the triple cover stitch for doing detail work.
I WISH I had my mom's old knee pumped (treadle?) Singer from the early 1900s, but she gave it to my aunt... Would be nice to sew fast with no electricity!
Have had several others handed down to me, that I ended up giving away to my other sisters. (Glad I kept the Viking though
