2011 line won't come out until the fall/winter.
Dig a little deeper and you will learn about the Custom... The biggest complaint about the Custom is that it's way over priced. With you getting it on sale, you wouldnt be doing that bad. I am pretty anti Burton as a whole because I disagree with how they manipulate the market, but $300 for a new Custom isn't so bad. I would personally save up and get the Never Summer, but I have hate for Burton.
So in all man, $300 isn't bad. My opinion stands that the Legacy is a higher quality stick and the 3 year warranty could really bail you out someday. Remember a warranty starts on the day that you buy the board. So keep your receipts.
