Stu Sweetow and his team at AV Consultants have provided excellent service to us year after year. The result is a wonderful collection of DVDs that preserve the lectures. The quality is so good that we have been able to reproduce and sell the DVDs. Stu is extremely easy to work with. He explains everything clearly, and is available if there are questions. AV Consultants also was the most cost-effective videography service when compared to others. I could not recommend him more highly.
