Where can I get a Dragonball Z boxset Collection?

I've been a die hard Dragonball fan since I was a kid (let say the age of Gohan's first appearance). I own the Dragonball GT Collection since I saw it on sale for $30 (crazy right)! Right now I really was wanting to see the crazy adventures they had again in Z, but I can't find the collection anywhere. I'm actually looking for Dragonball, Dragonball Z, and their movies (I know I'm way behind, I just really want to keep this collection till the day I die...maybe). I don't want anything used. I'm afraid of having scratched discs, so NO eBay.

So do you think you can find the Dragonball Z Collection anywhere, legit? It doesn't have to come with the movies or the original Dragonball (found one and it seem ok...I'll get it later) but if it does that's cool. The only thing I care about is the price I'm willing to go to $100 for the collection.

For any of you Dragonball fans that have seen Kai, do you think they have ruined it for censoring gore to make it child friendly? (Geez, I've watched it since I was 4)
