Asking who is the best builder is like asking you what kind of beer you drink, who makes the best car/truck, and if you like blonde/brunettes/redheads (or...gulp...baldies)
Call several builders, Jim @ Passion, Jeff @ Fast, Cameron @ K&T, Kim @ K&T, the list goes on.
See who treats you the best, who answers your questions AND asks you the right ones, gives you a good price (remember, you get what you pay for) and make your decision from there.
You're shorting yourself if you only call one builder...any one of those listed above or any other builder.
That's like shopping for a new car and buying the first one you see on the lot without sitting or even looking at other cars....
