.biz What's the Value? .com, .net, .biz etc..

[NowYaKnow]

Hi all,
I have only .com's. I see a number people buying and selling the other extensions.
So...if SEX.com sold for a reported $14mil and SEX.net sold for $450k...what are the variances for an average domain from its .com to other extensions and how would you rank them?

I realize that a number of specific words are worth more as .whatever for their particular business sector
IE: movies.mobi would be worth more than movies.nl no?

So, what do you think?
IE:movies.com
.net
.org
.biz
.info
.whatever :hehe:

Please give other examples.
Thanks
