This came up a week or so ago so you can check the archives for a longer list. I know of (heard some good things but haven't dealt with personally) frankg and Mancini's. Lots of friends have dealt with Burtonsville and been happy, and that's where the shop I hang out at sends all their customers (Vernon's Automotive in Laurel). It's in Burtonsville, just west of I95 off of hwy 198. The local gsca chapter gets together here in Laurel the first Tuesday of each month at 7 pm, at the Pizza Hut on Rt. 1 about 1 mile south of Hwy 32. Come out in two weeks and meet some new friends and get lots more input on machine shops.
