If you can get a pfaff 130, just go for it. Those old pfaffs are near indestructible. I once came across a 130 mated to an industrial servo (3/4 HP) and it was sewing diaper bags at industrial speeds with ease. That's all the sales pitch I needed to be a fan, any home use that can hold up sewing 5k stitches per minute sewing 4 layers of 1000 denier cordura has to be great.
