well my site is nearly finished design wise...

I have a spare link slot though on the nav bar that I was going to use for a links page..

However I am just not sure about whether I want to have a links page. What are your opinions on them ?

I think they look unproffesional, BUT I know they can contribute to a large amount of traffic. So what should I do ? I don't have a huge space available for loads of links so what should I do ? Just pick say what I think are the 10 best sites and see if I can swap links woth them ?

What do you think of links pages ?
