Popmuzik

I was wondering if any of you knows exactly how many remixes from Popmuzik
exists ?

I have heard the one on the LNOE single (the Pomart Mix) and the one at the
beginnig of the Popmart shows.
I 've also heard another one in which Bono sings slightly different than the
Popmart Mix

My questions are :

Is there any single or promo where I can find the original mix used at the
Popmart shows ?
There's a promo for Popmuzik (MUZIK1), which mix does this promo contains ?
Is this worth to pay $65 for it ?

Thanks in advance for your precious help
