recently i made myself a matter fabricator, but it needs an amplifier to make the UU, normally i'd use cobble for scrap, but GT hardmode makes the config in IC2 for no cobble to scrap default. currently i'm using fishers to make fish to make scrap, but I can never get the exact rate down to make an equilibrium. so i'm wondering if any of you know something else i could use.
EDIT: i am also low on space so things like tree farms are out of the question
