multiple trackers - multiple searches automation. any ideas plz?

like almost everybody now, i have access to multiple trackers, and while something simple can be downloaded no matter where from, for rarer stuff or for trackers that are not that easy with ratio things, it's a pain in the ass to do searches.. is there any way, maybe plugin for ff or some other way to make it easier? so i could enter the string, press enter and had searches results (in different pages of course) from the trackers that i choosed? from one side it's for music - i have a list of favourite bands, from other side - dvd's.. thanks

...hmm, after some researching, seems that peerspider is the best option for me
