My friends father in law got one, and he used the internet to get the best deal. When it comes time to check out dealers after building one. You can email them for availability, and he emailed something like 10 in a 50 mile radius. I live in a suburb of LA so we probably have even more then that in the same radius.
Plus he played the end of the month game during the week, and he got it for a couple hundred below invoice.
