done know gypsna!!! same experience here... the only thing i wonder when it comes to plastic is following: i got a pollinator, and when finished sieving, there is loads of stuff on the walls and the lid of the pollinator, to be honest, i never inspected those "grades" separatly, since i always was under the impression that the stuff on the walls was less interesting then the collection at the floor (normally i scrap the walls, the lid, and mix it to the "ground" portion), guess ill have to do a small & !!! short run (10 seconds or so) and then compare the grades, as soon i do it ill let you guys know what came out of it! thx very much for the pointer again
