$50 - $75 for a Rockchucker or Redding Boss, You can blast clean them with Brake Cleaner, be sure and lube it really good.
Yup. Go with green iron, and you won't go wrong!
AGREED. A 'Chucker in good used condition will still have a lot of years left in it.
I have two sitting in boxes....one was my brothers and the other was given to me by my wife, which is only two years old, neither will be sold. Who knows I might set them up later.
