Don't forget http://www.bullgooseshaving.net/ Phil has some good prices and excellent shipping rates.
I personally got my brush from http://www.penworks.us and I absolutely love it. Tony also great product, great price and low shipping.
Excellent suggestions on both of those.
I simply love my Penworks brush: top quality, without having to pay the brand name prices. It looks like a piece of art.
I can order from Phil on a Wednesday, and have my order by Friday. Phil is simply an amazing vendor, with a constantly growing stock of shaving supplies.
