In the Prism line it is an Ozone (out of production) or the Zephyr. The Zephyr seems to be a well liked, light wind choice here!
Are you only considering Prism? There are many other manufacturers out there to choose from. But Prism is a known, tried and true brand. The Kite Shoppe is a good online source, so too are ITW, Kite Connection, A Wind of Change, and Flying Smiles Kites Also offer several in other wind ranges too. Right now on ITW, there are sales on 2 kites - The Hydra and The Kymera. Both are good capable kites in the mid wind range. Nice thing both on sale for just over $100!
But it all depends on what wind range you want to fly in!
