A Power Rangers morpher is worth only about $80-100, and that's if it's complete (I'm a Power Rangers fan so sue me lol).
A replica Pack can go for $500 (for basic no electronics) and upwards to $1000 and over.
The Kenner Pack is worth around $90, and go higher depending on the condition and if it's complete or Mint in box.
The Extreme Ghostbusters pack, I'm telling you, it doesn't pop up as often as the Kenner pack, but it's not worth quiet as much. I can't really give an estimate.
