I invested 10 $ quite spontaneously, dunno why, maybe too much time on internet and I thought to recycle 6 $ I got from weblo.com :) .
Anyway... I got 1000 impressions for 10 $ and there is still more than 900 left. So far this test had got me 2 new followers.

Banner ads are shown in several twitter focused sites, most of my ads has been shown in twibes.com, secrettweet.com, friendorfollow.com
Good luck! :)
fyi... 7 more to go and I got my first 100 followers @ twitter. I have fairly passive strategy, so I guess it is ok result so far...
