Expired domains using Bluechip Backlinks?

Hello, has anyone of you tried using bluechip backlinks for purchasing expired domains with good metrics and authority? Untill now I used to do this manually but it requires too much time and too many checkings.

I need to know is it worth it, because their service is not cheap (it's about 100$ per month). Did you find any quality domains with authority or just some spammy domains? Since the owner of this service is Terry Kyle I consider it legit, but still got burned couple of times so I have to play it carefully

I highly appreciate any reply from BHW members who know what i'm asking here

It's still a crawler/scraping, and there are 100s of people constantly crawling/scraping. I can pretty much guarantee that there's almost nothing left worth crawling for, especially at that price point. But... I may be wrong...
