There should be some kind of sticked thread where all those cheap poachers, RBs, DCs and so on would be listed, because from time to time someone start a thread like this and people give the same answers like Rochina, Sanogo, Romario, Kara, Jenssen... It's like Groundhog Day.
When I need to find particular players I just use Google and type in something like: fmbase cheap striker/defender/playmaker and I always find what i had been looking for.
