This is a discussion on software that is similar to flopzilla, but free/cheaper? within the online poker forums, in the Poker Software & Tools section; looking for a something similar to flopzilla where i can input my hands/ranges prior to flop cards and see what they will hit.
Not sure if this is what you are looking for, but Pro Poker Tools. Jason Somerville uses it while on Twitch to discuss equity in whatever spot he is currently discussing. His commentary is very informative, and he talks to you, not down to you.
