Scrap/Scrap boxes work really well if you're not trying those. On another note any other form of power generation works, I guess, although you'd need a lot stored up if you're not going to be having large amounts generated through solar arrays or nuclear power. Geothermal with lava pumped from the nether could work, or even just MV Solar Arrays can regenerate power relatively quickly even if they can't keep up with the Mass Fabricator.
