domain Need input on these domains

[gnetsolutions]

i have the following domains, looking for some input on values:

sporecolony.com
sporecolony.net - related to the upcoming and probably to be a hit game Spore, by Will Wright, the creator of The Sims)

talkinvesting.net - PR3 domain, abandoned development but could be used for an investment type site

newswiire.com - Nintendo Wii news probably

cholesterol-facts.org - high paying keyword cholesterol

virtualizationwatch.com - some sort of news about increasingly important "virtualization" technologies

eptitio.us - mainly used for the word surreptitious, surr.eptitio.us

i would appreciate it if i can get some input on how much any of these may be worth.
