Another thing to keep in mind is to check if the actual website names you want are available... coz you'd be surprised how hard it can be to register a website name in this day and age...
Just recently my colleague registered a new company name online, but just before that we had another name picked out (which was available at the time), and the next day when we went to register it, it was taken...
So yeah, just keep in mind that URL names fly off the shelf real quick, so once you find one you like which is available, i wouldn't wait too long to register it...
Otherwise, if some one else buys it, you may have to pay a premium price just to get the domain name you want... and trust me when i say that can costs thousands of dollars at times...
