I was curious if there is a good way to come about with an approximate value for a domain name on my own without having to pay for a service. Reason being, is there is a domain name that I would like to register, that is not currently registered, that I would like to register simply to resell. However, I've never done this before, and need a way to see if it would be worth it at all to do it. It's not like it's so great I think I could make hundreds of dollars off of it, but I'm curious to see how much I could get. Any ideas?
