Metapower can reduce the metamagic cost to zero, but not the cost of the power itself. Also, it only applies to one power with one metapsionic feat (Also, Earth Power just prohibits you from expending your psionic focus on the power, rather than expending it. Still potentially annoying, but not mindnumbingly so).
Energy Current is nice, but even with EK it is a way off.
Edit: Being off-topic, since bestow power is banned, but metapower+linked power is a feasible start for a recharge setup. Then just add either SRD Torque of Power Preservation or Psicrystal Containment +midnight augmentation and you can get a bestow power linked bestow power for pp recharge fun.
