More Pod Woes!

I already wrote once what has happened with my songs in my iPod Shuffle. No adding more frustration to it.
All i did is put this iPod Shuffle in a different PC with iTunes. iTunes informs me that my iPod is synchronized with a differnt iTunes library and inorder to synchronized with the one in myt new PC, all the songs in my iPod will be deleted!!! Oops.
I have no way to just see the songs, delete only what i want, add only a set of songs into this iPod. Is this product worth a 100 bucks? Seriously!!
