When should I start using adbrite?

First of all, sorry if this is the wrong section. I just couldn’t figure out where better to put it :-\ But anyway, adsense is showing ads on my site that look very junk,y so I took it off. Now I want to use adbrite but my site isn’t too big yet. I’m wondering when I should start using adbrite and could possibly start making some money with it. And by that I mean once I start averaging what amount unique visitors a day/week/whatever. I’m aiming for 1000 visitors a day (which is a LONG ways off), should I wait till then?
Thanks
