There's a dealer in Macon, Hartley Bridge Rd. that sells Babylock. The closest to Macon is in Duluth. There's also one in Marietta. I believe the Babylock dealer also services Bernina. Their name is Magical Stitches.
There's also a Brother dealer in Macon that services Bernina but I wouldn't recommend them. I took my machine in to have the tension checked and cleaned. They charge an extra $25.00 to send the embroidery unit along with the machine. The dealer I bought my machine from in Kentucky never did that. Maybe all dealers charge extra to take the unit. They're not really very friendly there either.
