i am going to get this one:
Flip Video - Ultra Series
it's only $150 and my girlfriend said that it is perfect to throw into a diaper bag and go. she said all of her mom friends have big fancy ones and they hardly use it and she gets small video clips all the time. we went to the pool and she wipped it out and recorded her baby girl. it's small and so cute! (if you are looking for something a little more simple)
