We were really lucky in this area. There were more than a few Amiga stores way back when, BUT we had a place called Buried Treasure out towards Rockville. They carried most of the Commodore Line - but specialized in the Amiga. They would help user groups and individual users. As good as most Amiga shops were, this one stood above most of them.
Friendly, helpful, with a huge stock and a great technical staff.
This was a great place!
