Intext Advertising (for publishers)

Adsense has been going down lately and i am looking for alternate means of income, i am currently looking to try out in-text advertising and i am looking for guidance.
Can anyone who has used this networks before (kontera, infolinks) tell their experience on how these services are. Are they profitable? are they worth it?(for the annoyance they cause the visitors), did you notice an increase in bounce rate(drop in page views) after implementing it? which network is best? (most profitable)
For a computer blog with 25k+ monthly pageviews would it get a considerable income.
Any feedback would be appreciated, thanks.
