Hello Mike, just choose one of the many. Most programmers allow to choose many vendors for the same chip with identical pinning and specification.
I used a cheap programmer instead of the GQ-4X. The problem was that the chip is inside the circuit board and the supply voltage goes from the 93C56 to all the circuits. That causes the overload protection of the programmer to shut down the 5V. My workaround was to power the gauge with 12 V from the connector and voila ... I can read and write the EEPROM.
