I think I have replied to all of them. I received one or two PMs which might not have had/get replies as I specifically asked for names to be sent by e-mail.
I bought one domain which happened to be a good .org rather a .com.
Thanks to all for sending your e-mails.
Please no more names as I've got a feel now for what sort of names are being offered for the $100-$500 range and they're not really the sort of names I'm interested.
