Todd Stock of BACS is exceptionally knowledgeable on both PC and Mac. He got my systems humming in reasonably short order and he is very responsive to my requests for assistance.
In addition, I have used Mike Kushner who is very knowledgeable and personable. He has treated me very fairly in allowing me to return a phone system I purchased through him which I did not like.
I would recommend them to anyone who needs professional help with their computer systems.
