There is a new sewing machine guy at my LQS who I've not yet met. Happily, though they are a Bernina dealer, he works on all machines. We checked on Saturday to see if he could check and clean our new Featherweight (tension assembly is a little wonky - but I knew that when I bought it), and then dropped the machine off on Sunday. Eventually I'd like to take a Featherweight class so I can learn to do the maintenance myself.
Cheers, K
