Registration fee to MAYBE low $xx. And thats if someone wanted to trade two of their registered domains for yours. So max... Registration fee times (x) two. Try sticking with the .com's. There are still some worth while domain names that haven't been caught or are about to drop. Take your time and research some more. Besides .com's... the only other ones with any real value would be; .net, .org, .tv... and even then, .com still is the best all around. So I would say, stay away from anything else! 0_o Your domain has a nice keyword, however, your TLD of .net.cn really isn't in much demand at all.
