I just found this site called gotlinks.com they are like tla-ads but its for link exchange. It appears they also offer paid links as well for * $55 per month: 1000 links * $100 per month: 2000 links * $175 per month: 4000 links are they any good to work with ?
I think they place their adsense on your links pages if I'm not mistaken, so I wouldn't suggest using them.
