Agree ... you really do need to know more about the repair reasons!
Were the repairs "operator-caused"?
With the newer more computerized machines (which I think the 8200 is) ... it is way too easy for the operator to create the need for repairs.
I don't know the 8200, other than from knowing that others have always talked highly about it.
I have owned four Janomes and have always been impressed for what they were able to do ... and the only problems that I had, I caused myself!!
