I made a simple little mod that adjusts the tech tree so it displays the beaker costs of the various techs. It also will display if a given tech leads to a Trade Good, Super Project, Galactic Wonder, or Starbase Module. Just unzip the linked zipfile to C:\program files\Stardock\TotalGaming\GalCiv2\Data\English, adjust the path to fit where you installed to if need be. Mod was made with the GalCiv2_110_beta_032406-1, but should work with any version.
