I had a Janome 10000 which I upgraded to a 10001 and loved it. Had it for 7 years with no problems but did keep up with regular maintenance which I think is a major factor in any machine. I recently sold it and since I had a wonderful windfall, went with the Babylock Ellisimo instead of the 11000 because I don't like that movable screen and there were some features I wanted that weren't available on the 11000.
However, I will tell you that for a workhorse of a machine that I think will be around for a long time, you can't beat a Janome! Check with Ken's Sewing in Muscle Shoals, AL. They have been the national leading dealer of Janome for several years which means they might give you a better deal due to the quantity they sell. I have dealt with them for 30 years and they are very honest people and incredibly helpful.
