I know. This listing looks suspicious, but I'm imagining for a second that some random sellers got a bunch of old stock. At this price, I could get 3 Spiders per SecSavr Bay/Core/Somethn for like £4 more than 1 singular Super Infinity. That then gives me 24 steppers to work with, which after learning about how those cheap unipolar drivers work by just amplifying the waveform generated by the controller, I might need. I'm fine spending the calming 30+ minutes snipping pins and soldering capacitors on a bunch of stepper drivers for those kinds of gains.
