How much do you think the domain www.sawtalk.com is worth? - i think it could be developed into a very active community, saw is the name of a movie, that has 3 out at the moment, and saw4 coming out next year. So it wouldn't be hard to get alot of good content & members, just would require some work.
Idea behind the name is pretty good and if executed correctly could get you some good returns, but as of now the domain name itself is not worth more than reg fee.
