Define "low cost".

Depends upon what you want the 741 to do.

Yes,i can use all Dual Supply op-amps with single supply also,as long as input common mode range is not exceeded.
You can also use any "single supply" opamp with a dual supply with the same condition as above.
For detailed discussion regarding op-amp's & supply pin voltages refer to this thread:https://www.edaboard.com/threads/289723/
