I like it. It is easy to remember. This is something you would have to sell to an end user or develop it & get a lot more $$$.
With the way it is I say it is mid-high $xx... With development / getting traffic they way you are doing, developing PR & getting some revenue. I would say low - mid $xxx is easily achievable with a couple months with a few hours a week. Possibly more depending what you do. But as is you can still get profit from reg fee .
