They don't give much of a price break, but Carter's Country (4 stores in the Houston area) is where I bought my G2 and P61 LA. I've been shopping there for years, and have always had outstanding customer service.
I went right after the hurricane scare, and their selection was down accordingly. They said they'd have more in a week, but I didn't go back, because, as Dale Gribble from King of the Hill said "I'm weak, Hank!"
The dealer locater is a great idea.
