Anyone have a domain name generation site?

I have a script that generates domain names, and am wondering if anyone is doing any good with such a site.

Netflrms and namech3ap only pay for sales from your traffic that do not already have accounts with them - new registrations only.

G0daddy (and it looks like 123-reg.c0.uk) pays for sales regardless of whether or not the traffic you send them current accounts.

I imagine more commissions are earned from hosting sales rather than domain registrations, curious if much $ can be made from registrations.
