Check the Namepros "Advertising Forum" ... I'm not sure how long ago it was, but I'm sure there were some there for purchase. They are not free like the free $8.95 Reseller accounts, or even moderately priced (as mentioned) like the $7.95 Reseller account ... so pricing and making sure that it's for you by asking questions is advised prior to purchase. $6.95/per is a HECK of a competitive price and when complemented with Enom's easy and value-added services, it's a very attractive alternative, IMHO.
Best of Luck.
Always be sure, whichever account you decide to go with, that the ETP is a good guy and that the account has been in existance for a while. And try not to keep it empty because then it can be deleted ie. just push a name into that particular account. Good luck... having a 6.95 account feels powerful!
Most of Enom ETP had established business presence already and they will protect to keep their existing resellers/clients.
A good sign is to find out how long they are in the domain business or other related services. Don't fall to a nice short-term plan. Remember some of them is just a buy and sell business. So go out there and search before you bind your business.
