Yea, I kinda have to agree with ya on your points - I had attempted my first seat cover (90-ish Cavalier bucket) last weekend and the limited space on the right really made things interesting. I will say that I was able to cram 3 layers of 1/2" sewfoam/gripstitch and vinyl assemblies under the foot, but ya had to watch and make sure it fed correctly and didn't get hung up. I will say that the smaller HP motor was perfectly adequate for what I've done so far. There's 2 sets of belts/pullies so it's geared down quite a bit for the increased torque - don't know how the speed compares to a real industrial machine except that it's plenty fast for my skill level.
As for feet, its got the standard, left-zipper, right-zipper, and leather foot - mainly the basics. The leather foot doesn't have the sharp teeth that the standard one does, and both the leather & standard have channels for piping.
It works good for shifter boots, though
