I have a Brother 1500s. I use it on a Gracie II frame. I am on the lookout for another one, used. I would like it for FMQ on a table. I found a used one with a GQM, but she wanted $1000 for both. I passed the # to my sister and she got both for $400. What a deal . It runs so smooth and I do love it. It has a thread cutter but I don't know what you mean by 'auto trim'. I was looking at the Juki when I bought the Brother. The Brother dealer sold me when he compared the replacement cost for several parts, such as the thread cutter. It was appx $100 difference. The Juki has a few more gadgets like the knee lifter and foot pedel thread cutter, but also cost more. The Brother dosn't have the knee lifter option that I am aware of, but it does have a push button thread cutter.
