I would give the following appraisals for the names you have listed:
VirtualTomorrow.com [ Mid-High XXX ]
>> no other extensions taken >> valuable keywords >> makes sense
>>similar websites have not been currently used with those two keywords together.
WarezSolution.com [ XX ]
>> no other extensions taken >> subpar keyword combination >>
>>minimal similar websites has been listed in the .COM [softwarezsolutions.com]
GreatToTalk.com [ low XXX ]
>> Combination is memorable -- phrase is not overly popular ; however I can see this being used in a tele-startup.
Take care!
