I had a Brother 1500 for years. Wonderful machine then it started to mess up. Three times in the shop for the same thing and I went to a Juki machine siminar by a juki tech/rep. I learned so much and he explained why my Brother's thread cutter was freezing up my machine. Fpr some reason I was using a bobbin with holes around the rim. That's a big no no. Always use the exact same bobbins for these high speed machine. I bought a Juki that was traded in for cheap and got the Brother repaired again. Put in the correct bobbin and so far haven't had a bit of trouble. (the Brother repairman was clueless, just kept putting in a new thread cutter) I was really impressed with the Juki rep knowledge of both machines. He didn't say anything bad about the Brother but showed the differences inside and out. I use the Juki the most for machine quilting. I have a better feel using it. Hard to explain but most know what I mean.
