Amost ashamed to say.....I have a 9 year old Jamone MC10000, a 3 year old Brother PR620 (six needle) and an 18 month old Brother Quattro_Innov-'is 6000D. I love them all and all are very user friendly and work well. Can honestly say (touch wood) that I have had no problems with either of them.
You can tell I am a machine embroidery addict as well. My very first embroidery machine was a Janome MC9000, 14 years ago.
