I think this lady is wrong about longarms needing more frequent maintenance. Most longarmers don't take their machines in, unless there's a severe problem, because their dealers are not usually nearby and the machines are meant to be cleaned, oiled, and maintained by the owner, much like vintage sewing machines. I know there are fewer places for lint to hide in my Innova than in my Bernina, and I also know that I can reach the (single) regular oiling point very easily (the bobbin hook). There is one other place that can occasionally be oiled (although not required), and that's also easily reached. As a Viking dealer, perhaps she doesn't frequently see longarms? Or perhaps she is familiar with only one brand? I frequent several longarm yahoo groups, and I don't remember anyone ever talking about needing to take their longarm in for regular servicing.
