Hi TheShrin,
My Appraisal for DVDKingpin.com:
Potential End User Value: mid$xxx-high$xxx (post development)
Reseller Value: low-mid $xx
What I Would Pay: reg fee (Not An Offer!)
My suggestion would be to develop a brand with this domain, and develop a site that either reviews dvd's or sells them. You might be smart to develop a site around the sale of "Used" DVD's as there will be an opportunity in that market as the BlueRay discs take over (and they will). This would provide some longevity in the value of the domain and provide a potential end-user with a bit of confidence.
The other two domains I would say are harder to sell, and you may not get much more than reg fee unless you develop them. Good luck with it all.
Cheers,
Kris
