PICkit s/w looks like it works well. Even to the point of reflashing back to MPLAB mode. MPLAB sent PIC16F57 details to the PICkit3 and then could not find the 16F57.
I am using the GOSONO PCB with its ZIF socket and the jumpers set for the F57. (Setting per the silk screen on the back of the GOSONO PCB.)
FWIW, Parts ordered from Amazon.
