I am what is known as an advanced collector of Classic US stamps. Like so many stamp collectors, I returned to the hobby only four years ago. Upon a professional recommendation, I was told to go to Northlake Stamp and Coin as it was ""the only dealer in this quadrant of the country"" to go. I have not been disappointed. I have received excellent advice re: albums, issues, and supplies. I am never rushed. I pay more at S&C; however, everything is guaranteed. Casual collectors are treated the same way.
Pros: a collector himself; very knowledgeable
Cons: for some, he may seem expensive; crowded & cluttered
