I like the look of 179 and think that it is a really cool image. Some of the other images you pointed out look really nice in the concept of their image. My point would be how would it look once you made it the favicon for the site, and the forum icon as well as the homepage splash image?
I started to say that 153 is probably too similar to the current logo but 65 is of the same concept, granted I do like the image for 65 more.
What do you think of #84? I didn't even realize that the winner had been selected.
