Sewing machine repair recommendations received

Here’s the list of repair places recommended to me when I inquired: Altomari. Mt. Lebanon H. Matthie Repair. 412-341-0827 The Sewing Store. Tarentum Ron’s Sewing Machine Repair. Dormont. Thornton’s. Babcock Road. I took mine to Thornton’s but the wait is very long (weeks). That was OK for me as I have another machine but I don’t know what the turn-around would be at any of the other places.
