I have used industrial machines. I like them for the power - speed is very nice, too. I miss it on the home machines BUT I don't max it out on an industrial - never - I seem to max it out on the home machines a lot though. I think you have to be very sure of what you are doing to use an industrial machine.
Steve, I have a 241-13 and it makes the tiniest stitches which aren't good for canvas, etc... otherwise I'd love it. I don't know how to make the stitches any longer - surgery maybe... there is some sort of limit on the stitch length in the wheel. I've considered just getting a different head on the rig but I love the machine - stitches not so much. I'm wishing I still had my 411 or what ever it was walking foot. That thing would sew through anything and not even hick-up.
