PCForums.info looks quite good written down, but the plural hurts it a little and so does the extension... still more than reg. fee I think, low/mid $xx
Developed though... could be something really nice.
plural hurts it and .info doesn't fit the name quite well, I have to say mid $xx, but as for the plural, it could be developed into forums directory. Good luck on the sale or development.
I am not sure .info is the best TLD for that usage. I would go for .com then .org but .net would fit nicely here. Still a good name with excellent potential for development. If I had to put a price tag on it: low $$$. IMO value resides in development more than resale.
