I'm after a new travel cup. It must be leakproof (so it can go in a bag without spilling) and have an easy drinking mechanism. I don't want to have to unscrew the whole thing like a Thermos flask, but I currently have a Contigo (Byron?) one currently which has a hole in a dip in the lid, I find it spills everywhere when trying to drink!
Dishwasherable would be good but not essential.
Price up to £40 but the cheaper the better.
Nice colours/designs a welcome bonus!
