Yeah, tough to find used. I was lucky enough to find one on here from BrunsNick a number of years ago for a good price and then sold it. Then I started drilling and needed one again and got lucky again. I'm not drilling anymore, but I still have my pro-sect since I never know when I might need one again and I'll be damned if I'm going to pay full price for one, lol.
Good luck with your search.
