Personally IMO think-easy.com is your best.
The hypen kinda kills it, though it is still a brandable phrase.
The rest are reg. free, i cant see any development potential, as they don't seem to really relate to any product or service.
Take some time reading through NamePros to really understand what makes a good domain name and also the types of domain names to buy if you are looking for a quick flip and stick to .com, .biz are extremely difficult to sell unless its an ultra premium one word name.
