I must agree the Jem Gold is remarkably quiet (compared to others of same type). I like the MyStyle 100..it fits your criteria. Length is adjustable on all stitches and width adjustable on zig-zag only...the other few stitches are fixed. I don't know if Jem Gold has adjustable width or not. Pfaff Select 4.2 is nice too but if quiet is top priority...then look for an older metal kenmore that offers the basic stitches. They tend to crop up often and most are in nice condition. Singers are nice too (and quiet) but so many are straight-stitch only..except 401/500 series and the 247 made in Italy that offers just straight and zig-zag. I don't need another machine but would buy a 403 (uses cams for dec stitches) if i could ever find one...No free-arm tho.
