Posthole Digger Need 3 Point/PTO Hole Digger/Auger

[RABMan]

I have an old MF 135 and I need to find/buy a Post Hole Digger/Auger. I am leary of used ones, so I am leaning towards a new one. I would like a 9" and a 16" auger with a rock bit. I need to be able to go about 48" deep. Any suggestions??
