Replacement for 747 opamp (dual 741)
Usually asking for products/parts is off-topic but since this can benefit anyone who wants something better than a 741, I'm making an exception.

There are literally hundreds of suitable 741 replacement opamps.

The parts you list are waaaay too expensive. They likely have some special properties only few designs would need.

You should not be looking for a 741 replacement per sé but more a "generic opamp". 

There are very usable opamps to be had for much less money. Like LM358, 10 for 1 Euro (shipping included!) on Ebay

other examples: MCP602, CA3140, TLC271

Most of these have versions with 1, 2 or 4 opamps in one housing.

You will have to compare the datasheets to see what suits your needs. Do pay attention to the supply voltage for these opamps as those can vary.
