I have an electric lift for my sewing machine but not my serger. After a year of wrestling fabric I caved and got a sew steady. It's been great. Price depends on what size you get. Prices are competitive among the websites with the "junior" at around 60. They go up with the size. If you think of it as "another template or tool" vs the mint you paid for the machine-it's not much for the benefits. Before you buy find the lowest prices then check retailmenot.com for an additional discount code. Good luck and have fun.
