Showcasing.com acquired. Appropriate for domain marketplace?

I recently acquired Showcasing.com and I wonder you think it is appropriate for domain marketplace.  I am in the process of developing a site for my domains and struggling to find an appropriate domains. I was thinking of DnSupermarket.com , DeliciousNames.com or BuyGenericDomainNames.com . Now I am thinking of using  Showcasing.com, I appreciate your comments.
