I've purchased from Potter's 1x at a Suzuki Celebration but haven't visited the shop. Mr. Potter was very helpful and friendly. Although my instrument wasn't from him, he helped me cover up some blemishes on my violin on the spot after I bought his book on Home Repairs (great for any violin player or teacher). He also lent out a violin to a little girl while he did an emergency repair at the Celebration. She had broke the bridge. It was ready that afternoon for the concert.
