As a whole, the modded MC community has been slowly distancing itself from Buildcraft and going to RF for a large number of reasons which need not be discussed here. Extra Utilites can now run as a pretty decent BC replacement with the pipes, ender quarry, and ender pump. Anyhow is there a good replacement out there for the filler? All I care about is that it can flatten large tracts of land, not make the structures.
