I decided to get one as the Big LBS is having a sale, went up and they had none left but could get one in a few days for me. Being an impatient bugger I just bought one of their own branded ones. Used it today and it was just fine, only 1.5L but I still had water left in it after a 4 hour ride today.
It has always seemed daft to me that you spend ages making a bike light or spend a fortune buying a light one, and then strap a couple of kilos of water to it when you go out for a ride.
