My first one I bought from my dealer for $39.95. Absolutely love it, it is a necessity as far as I'm concerned. Last year, Shoppers Rule had them on sale for $24.95 and I bought 2 more, plus a couple extra bases. Glad I did, since this year I got a new machine and can leave the old one on my Pfaff for going to classes. Also put one on my serger and kept one for a spare. Expensive, but they are worth it if you have aging eyes like mine and mainly do your sewing at night.
