I just bought a set, 2 motors as new £150 the pair.
I also bought this below.
Its NOT a lighting module. The seller is a dummy. Its a lighting, + 6 channel seating module same as on my Q700 and Salsa chairs. I now have 3 spares. Its an ISM6L so 6 channel plus lighting. I offered £20.

I watch ebay all the time. When theres a bargain esp if they are hard to find for a year at a time I BUY. My shelf is full of cheap spares. Enough to build 3 full all singing/dancing R-Net powerchairs! Cables, joysticks, battery looms, motors, etc.
