domain Poker Tutorial Domains Appraisal Request

[Domainating]

Hi...

I have the following Poker Tutorial Domains that I would like to valuate. As you may well know, this is a rather unique market.

HowToWinHoldem [set of .com & .net]
PokerTutorialDVD [dot com]
PokerTutorialVideo [dot com]
PokerTutorialVideos [dot com]

These are mine and I am just looking for some idea on value, although they are for sale. What do you think these are worth?

I'm actually wondering whether or not to renew these names, right now. I am reducing my portfolio big time. But I don't want to get rid of any good domains.

Thanks in advance for your feedback, I do appreciate it.
