Best beaker for a 1 year old?

[Bonfire2010]

My 1 year old no longer uses a bottle and drinks from a doidy cup when we are at home, but I am looking for a beaker for when we are out and about. Any recommendations gratefully received as there are so many on the market!

I found that the basic Boots sippy cup (free flow, but with a fold down top) was the one that Miss Oi would drink the most amount of water from.
