I've had a Kenmore serviced at the Sew 'n' Vac at Normandy Plaza on Baltimore Pike just over the bridge into Howard County. As I recall, it cost about $70 and the store is moving more and more into full quilt store status!! Lovely people selling brand new Pfaff all embroidery supplies and I haven't dared to look at the fabric in the back room.
Also had major repair at tiny store in Laurel MD on FW purchased broken from estate sale: the man just chuckled when I told him my husband could fix it but I wanted the repairs done in my lifetime!!
