Pros: endless stitching capabilities, knee operated foot lifter, all accessories fit in your machine cover.
Cons: expensive and still doesn't compare to an industrial sewing machine.
I am employed as a full-time tailor and have been sewing for 2.5 years. I use an industrial Pfaff at work, and about a year ago I bought the Artista 165e. (comparable to the 170) The bernina is an extraordinary machine. It is better than any home sewing machine I have ever used beyond compare. The stitching capabilities seem to be endless and I have had few problems with the machine itself. Although for the amount of money I paid, I did expect more from it. I just can't help but miss the industrial Pfaff. I made the choice of the bernina mainly because of its being portable. The knee operated foot lifter is a big plus. The pfaff at work has one and I find it almost impossible to sew now without one. It is one of the best and unique features to the Bernina sewing machine family. Although I truly love my bernina and am not considering trading it in for any reason, if I were to give anyone advice on buying a sewing machine it would be this: if you are willing to spend the money anyways, without a doubt- BUY AN INDUSTRIAL SEWING MACHINE! then buy a second cheaper or used machine with all the fancy stitches. An industrial machine is WELL worth the bulk.
