Gundams AND Evangelion... my dear sir you are indeed a connoisseur of mech culture...
I'm not going to scroll down any further tonight (it's late) so forgive me if you've already done this and I'm missing out (point me if if so!) but how about some Aestivalis, MechWarrior/BattleTech or Bubblegum Crisis (not huge scale but still mech-suits)?
