$0 imo. If you're going to spend $ to register a speculative name, .com is all you need. There are premium 1-worders in the .us, .biz and .tv tld out there because those tlds are usually not worth much. It looks like you spent at least $100 on those. I'd suggest reading more of this forum and others before registering more names like that. Good luck and welcome to NP.
