I got a few that recently got face lifts.

From either of those 2 sites I have regular exchanges from the links pages, OR I have a very limited number of content page links (anchor text only). For a content page link I only ask for a content page link back.
In addition to that, please look at this thread.

We could exchange footer links from the sportsbook page there, or from one of the sportsbooks review pages if you are interested.
If any of this interests you, drop me a pm and we can discuss it further.
