Electronic Dictionaries/Translators

[David]

What are some of the best hand-held electronic dictionaries out there? I'm tired of having to be distracted from reading a novel in spanish by having to look up a word in the dictionary. I usually get distracted for a few minutes. I can get by reading the whole chapter, but I rarely go back to look up words I didn't know. I think it would be easier just to quickly type them in, find out the definition, and continue reading.

So I am looking to buy one that would be easy to travel with, offers a large vocabulary, and is possibly able to be used with several languages. Any suggestions would be appreciated. Thanks!
