#1 - I like the idea of having something a little more abstract. Is that a bow tie? One of the main features that I would like to stand out is the name "Molding Search.Com" I was thinking about some good creative font ideas for that, and then perhaps nailing down the logo. I'm thinking the Logo itself might be good as a single creative "M" with maybe a modern compass or something. I there a way to may the M and the S have dots on them in the actual name?
Agus, I like your initial design #3. Maybe it would look cool incorporated with the compass idea that i'm going towards. Check out my top ranked designs to see what I mean.
