There is an ad on FBMP offering them for $10 no bladder and the fronts cut out already. Debating on getting 6 even though I don't have much room and can pick some up out at Bunny's place, just a little hard to get to.
It depends, will you regret it if you don't jump on a good deal? Can't touch them here for that price. Generally it's around $100 So I have none.
