WTT / WTS: Omron NX-ECC201 Coupler + I/O Kit (Looking for Differential Encoder M

Hi everyone,
I have a few Omron NX kits available, exactly as shown in the picture. I want to trade one of these kits for an encoder module or sell it.
The kit includes:
• 1x NX-ECC201 (EtherCAT Coupler)
• 3x NX-ID5342 (High-Speed Input Modules, 16 pins each, 48 total inputs)
• 2x NX-OD5121 (High-Speed Output Modules, 16 pins each, 32 total outputs)
I have already tested the coupler and toggled the output module LEDs directly from a Linux terminal via EtherCAT. I pulled the original ESI XML files from Sysmac Studio and can provide them if needed.
What I am looking for:
• Omron NX-EC0142 or NX-EC0132 (differential encoder modules with digital inputs)
Since I am doing this to learn EtherCAT, I am flexible and open to other brands. I am also willing to trade one of my kits for a Beckhoff EtherCAT coupler combined with a differential encoder input module.
Thanks!
