The first pair that I purchased were Machingers, now I'm using Graberoos.I have used the cheapo's also, but they don't give you the control you want. Not only do Machingers control the feed of the fabric into your machine, but I have found that it helps emmensely with my Arthritis. I love them, and won't quilt anymore without another pair. (The Graberoos I'm using now, are better then nothing- but give me Machingers again. PLEASE????
