The Magma Crucible + Geothermal Gen is so powerful that breaking into the Nether is one of my first priorities. It also allows a single breakout point for BC/IC2 power (lava running TE magma engines for BC, GeoTherm for IC2).
At first, manually mining rack and carrying it back is a viable bootstrap to an automated system with a quarry, as the Crucibles are efficient. Once a quarry is running, you'll need some lava storage:
A mere 3 quarry runs (standard 9x9) in the nether filled this supertank, with a silver chest full of Nrack left over as buffer. YMMV on this amount, based on where you set up the nether quarry. I scaffold to the top.
I would prefer to replace the kludgy Nether Chest / BC pipe solution with Mystcraft portals and rails, but I haven't gotten around to discovering crystals yet.
