I have found the ATG lighting website to be one of the best out there, with minor glitches on the searches sometimes. By narrowing the criteria for my search, I found this perfect chandelier, which was exaclty what I was looking for.
ATG has an extensive lighting inventory, which keeps me coming back. ATG could expand their inventory to include lesser known, or more avant garde, designers.
In the past, I have found that if there are issues with an order, ATG's customer service isn't the best.
Overall, though, I am a happy customer.
