I think that as a domain alone it has very little value, as I doubt it receives type-in traffic, meaning any prospective buyer could probably register a similarly suitable name for reg-fee. If developed into a business, I think I would sign up
Yes, but this is not traffic. Does the name get type-in traffic? It should usually have ovt with extension to have any significant traffic. What the figures you quoted show is potential, i.e. there are a lot of people searching for this type of thing, so with a little development, seo work etc- you could be on a winner. That was what I meant earlier, sorry if it came out too negative.
