Reg fee at most. Don't register names just based on computer appraisials. First ask yourself how much would I pay if I would be buying this domain.
Just proves how much of a total joke that site is, & I presume you mean Nameboy, not Gameboy. Honestly, this name is worth $0 without development.
I should have put the wink smiley. They're all bullshit these Domain Appraisals. And peoples opinions too for that matter. A domain name is worth what someone is willing to pay for it. End of story. Would you have picked "YouTube" for a video-sharing site?
