It's a pretty nice name, but I'm not sure how much you'll really get for it. My guess would be around the reg fee, but I really don't know much about "bios"
I just posted a similar question on another forum an I already received an offer of 300$. I didn't purchased this domain for re-sale. I am not in this business. I just don't want it anymore. This is why I am asking here. Should I sell it for 300$ ? Or should I wait more?
I don't know much about domain appraisals, but the domain name is great. However there might or might not be a trademark issue here, that the buyer should be aware of. Other than that the domain is great.
