To answer the questions of a number of people - I am not looking for the absolute lowest price, quality and stability of the registrar is important and I am certainly not going to switch registrars after a year just to save $1 per domain. As to the question of what the domains are for...I'll yet you all know after they have been purchased and set up. Thanks for the thoughts.
If you are looking for quality & stability of a registrar, the most respected in the domaining industry is Moniker. If you contact them directly letting them know that you are looking to buy a lot of domains, they will definately do a deal for you.
