For any PDA, make a new state and do an epsilon transition to the start state and change the start state to the new state.
Similarly make a new state and make an epsilon transition from all accept states to this new state. Now, make another new state and make an epsilon transition from the new state to this one and make this final new state the only accept state.
Thus we get a simple PDA for any given PDA (thanks to epsilon transitions). Now, is this possible without epsilon transition?
