Good luck on finding an Epic Max under $275 - $300
Just recently I sold my old Rogue for $200, my old Mavrik Sub Zero, head only for $200 and those are older generation club. Hello I sold my g410 with stock alta shaft for $300.
You could find an old epic flash or GBB Epic in your price range, but not last year's model.
Callaway Preowned is a great reference for what people will sell for. The cheapest they have listed is around $330 in the lowest condition rating
Good luck on your search
