ripper bucket on the cat 375 ex -a 1 million machine if bought new-bought in San Diego for I'm guessing ca 100k and refurbished themselves for maybe 50k as grajekk points out,so this is the kind of economy Bob employed as a mechanically astute person to save costs,though some other things like the crusher were bought brand new for 250,000,and cat 740 haulers would be 800k brand new-dont know what they paid for them
