I have had janome 1600P machine for almost 3 years & have not used it apart to try to set it up & each time I have had problems i have it set up on a John Watts quilting frame I have changed the needle at least 5 times I'm using shmets Jeans needle & guittamenthread made in germany i have a friend who is very experienced with janome machines & she can't work out what is wrong with it considering I have spent over $3000.00 on it I would expect it should perform much better & be almost hassle free when I'm trying to quilt the machine sounds as if the needle has a barb on it & keeps catching & has very big stitches if I try & go faster with it it is worse than ever I am getting to be very frustrated with it & am almost ready to throw it in the river if I cannot get some stisfactory outcome I will not be giving very good reviews of it & certainly will not recommend it to anybody I've had a gut full of it
