I just got the Janome Horrizon, but I haven't done to much with it yet. I'm sure I'll love it. I had a Janome 6260 & I had no complaints.

I have the Bernina 820. If money was no object I would buy another Bernina, so I have one on my frame, and one on my sewing table. As I have said before, you get what you pay for, the Bernina machines may be expensive, but the Bernina customer service is priceless.

I have a Bernina 820 and I love it. . . . But I am a gadget person. I just love all the neat things it does, the fun things I'm learning, etc. BUT no one machine does everything perfectly. I've had them all and each had it's good points. I still think the Viking Saphire was the best for just piecing. No I'm not giving up my Bernina but that old Saphire was a gem.
I really think the machine you like depends on what kind of sewing you do, your like/dislike of new gadgets, patience in learning ways and the list goes on. Try as many as you can.
