I used Gass camera last year when my T1i sensor got incredibly dusty and I then followed internet instructions on how to clean it myself (and failed). Though he gave me some gentle teasing about attempting to do such delicate work myself, he then accepted my camera, and as an out of town person, offered me the courtesy of doing it as soon as he was finished with the project he was in the middle of and giving me a call when it was completed. I went to visit a friend about a half hour from his shop and was surprised at how fast the turnaround was.
