I know quite a few people who use it semi-professionally. They are very pleased with it. I thought the speed was 1000 spm max. I like the big frames and the capframe.
Thank you I am just learning from scratach, and just got janomie 11000 for Christmas just trying to figure out what all it will do.
I haven't studied them, so I really can't make an informed comment except to say that the speed you have listed seems a bit slow to me.
Dollars too much for me, since I am hobby only. I use Designer 1 and still lots to learn on it. Good luck.
