My advice: don't reg anything at Network solutions; in the long run, they end up being a costly choice and are no longer considered "premier."
Go Daddy and Domainmonster are my favorites.
I rely on drop companies for my aftermarket needs: Snapnames and Namejet, mainly. But I prefer Go Daddy auctions.
I doubt if anyone is going to share "trade secrets" regarding dropcatching technology; don't take it personally--it's just the nature of this business.
