Domains 4 Sale?

I started in the adult biz about 6 months or so ago, and i didn't really know what i was doing. I knew how to build websites, but not enough about the biz to make very much of a living. I started out trying to go big right away, like a dumbass, and thought the more sites i have the better. Well it didn't work that way, and as i ran out of money to keep purchasing quality traffic, my sites started dying along with the trades. Im now thinking of selling a few of my sites to make some $$$ to focus on making a couple of big sites, instead of a ton of little sites. I don't want to get ripped off and so im asking for honest opinions please on what a site might be worth. These are TGP sites running either my own sponsor hosted galleries, or using chokers GS3 program. Im not for sure selling them, i just want to get some feelers for what they may be worth and if the right price comes along, i would probably sell them.

http://www.peterspanker.com was at one time a 7-9k per day site that is now down to about 1k per day. This site has a PR2

http://www.harrybeever.com was at one time a 5-6k per day site that is now down to about 1k per day. This site has a PR1

http://www.woodystroker.com was at one time a 2-3k per day site that is now down to about 800 per day. This site has a PR4

http://www.xxxratedsex.net was at one time a 5-7k per day site that is now down to about 1100 per day. This site has a PR3

Again, please be honest as i don't really know what a site is worth or what it's worth is really based on. Traffic + PR? Just traffic? Just PR?

Thanks in advance to all of you that give an honest opinion, offer or advice.
