Eric,
I live in Houston and was treated at MDACC. My cousin, a well respected radiologist in town recommened that I go for treatment to Methodist Hospital, which is private, where I would get more personal treatment. I opted for MDACC. It does sometimes feel like a cattle call, but, as Brian said, they know what they are doing.
By the way, if you come to Houston, I will personally get a couple of Astros tickets and take you to the game. Even better if the Diamondbacks are in town ( unless that darn Randy Johnson is pitching!).
