I have the Baby Lock Imagine Wave and a Baby Lock Cover Stitch. The Serger I got for half price at Nancy' Notions ( 45 minutes away!) as it was a floor model. The cover stitch was 35% off. They are wonderful! I took them out of the box and have not had to touch the tension! They both have the "air threading" which is fantastic! I use the Serger for doll clothes, garment sewing--and dog under wear--for dogs in heat. The cover stitch I use for decorative stitching on shirts or whatever. I have used the serger for hemming napkins and table cloths for friends. I have not used them for quilting--yet. If you have the money and want to play, why not?! I would be concerned that the cheaper models may need some tension adjusting and not have the air looper threading. I would not like that. Am I spoiled--YEP, but I work hard for my "play money" to support by sewing and horse habits!!
