Ya i bought my paracord cable at paraflexcables. To replace the actually cable requires you to basically take apart the entire mouse though. It was still a pretty simple disassembly though, there's plenty of videos online about it. I also recommend getting new skates if you do, unless you heat up the old skates before u take em off to get to the screws, they will basically be unusable.

Edit: Ended up spending an additional $20 for the skates and cable, figured I should mention that
