.Us Domain Or .Biz

I have Some Cool ideas in mind, i m planning to buy some premium domains , Solely for the purpose of reselling them at a higher price, all the other tlds are gone, only .biz or .us domains are available, kindly suggest me .biz domains are good or .us


Also, i recently bought discountmovies.org kindly appraise this domain.

N make the domains relevant to their tld. So myhome.biz n atlanta.us

discountmovies.org to me is worth $10

hmm, nice idea, bt the issue is i dont have geography domains
