So what’s the landscape of agencies these days? I see a lot of BI and OneCollection. What else is out there that is safe and operational?

Almost all the old agencies are gone.  Chloe's (busted), RSG (retired), K-orgs (numerous busts), Sammi the booker (in hiding), Third Date Assisting (disappeared but some of those girls are still around), Nina's Diamonds (retired?), etc.  

I suppose there was always around two dominant ones. It’s just there’s a lack of variety it seems.
