I do, and it fits Greg's usual MO of trying to force players to use his machines for even the most basic vanilla tasks, but neither choice is an appealing one, you can either pray to the Random Number Gods to find a dungeon with either steel or fire charges in order to access the Nether or you can expend an obscene amount of resources (read almost 200 refined iron, over a hundred rubber, and a whole slew of other resources to construct the most basic industrial blast furnace possible) and supply it with a constant 128 EU power source due to its lack of internal power storage just to get access to flint and steel.
Kind of a moot point, though. Do you honestly plan on ever touching Unhinged?
