Well, golfclubsnews.com isn't very memorable (it's the plural that creates the prob ... golfclubnews would work MUCH better) ... and golfdsecond.com might be more easily recalled ... that might be factored in to value, but I think those values are usually based on whether there are any links coming to them and how long the site has been around.
Did you check whether Yahoo or Google has backlinks to either of the domains?
You might want to check this thread on domain names for feedback on
Nameboy.
