Yep, I'm considering a/some prime/s as well but since it'll be my first camera with interchangeable lens system I'm a bit hesitant. Since I'll still want the flexibility a power zoom gives while traveling.

Here are a few of mine:
Bottom line: The kit zooms are genuine bargains. Buy them and you will discover, coming from a non-interchangeable lens camera, what focal lengths you are most likely to use.
And again: ignore the bashers.
