lama-
I understand if this is out of your price range, but its a huge step up from Mitchell for not much more money.
Jim Snyder makes really excellent paddles which will last a long time with proper respect. In my opinion they are second only to ones from Keith Backlund(good luck getting a Backlund).
Jim will make your paddle to order, taking into consideration what you'll use it for, your hand size, strength, etc. The tips and edging are excellent and the paddles have great feel in the water. The final bonus is that these paddles are the best ever secret weapon for preventing tendonitis.
My Snyder paddle has performed great for the 3years I've had it in everything from raft guideing Gore Canyon to running OC2 on the Salt River Canyon.
