    Ok Spike -- you are the one who said "better", here you go:

    Use the current Russian RD-180 engines [1] (or RD-170 engines)
    or the SSME [2] (take into account fuel/weight differences)
    and get me a first stage booster with Saturn V liftoff capacity.

    Understood -- which is why I thought I had asked the question
    as to whether the Energia could still be built (and how much
    it might cost) though perhaps I forgot to mention it.

    *But* aren't the RD-180's being built in the U.S.?

    Then throw in some discussion about costs to bring the 1st
    stage back for reuse (SSME can be reused -- I'm not sure about
    the RD-180's) -- there has to be some cost involved getting
    it back to Earth without having it burn up in the atmosphere.

    (Where the hell do the Russian 1st stage boosters end up anyway?
    Someplace in the Pacific?)
