Bookshelf Speakers For 350 Or Less?? new & used

Hi,

A female friend asked me to recommend some bookshelf speakers for $350 or less, but I'm not too familiar with many of those models (I've heard the Mission 731i at $200-ish, but not much else). Which used or new (perhaps manufacturer direct?) models would you folks recommend in that price range?

Her receiver / CD combo is Sony / JVC mass market stuff. She listens to a lot of classical and some acoustic-based rock/pop. Most of her listening is probably background while she's cooking or roaming the house, but she is a musician and she does *listen*.

Any info would be appreciated, including recommendations that cost less than $350.

Thanks,

Phil
