Yeah, I was so eager for a fix that I googled for a Filco Replacement Cable (Pexon was one of the first results); and I pulled the trigger on a Detachable Filco USB Bundle right then and there. So for anyone who's wondering how much it costs for the detachable usb cable bundle and shipping to the US, it's $47.83.
I already opened up my Filco and pulled out the cable and it looks like I can salvage it. The malfunctioning part was occurring near the pin header, so when I have some time I'm going to cut up the faulty area and rejoin the wire. Luckily, I have some soldering experience (and equipment) to pull that off. I was just impressed that they're was a professional detachable mod available for purchase (Pexon) that I figured "What the hey. I've spent so much on keyboards that $50 seemed reasonable."
Of course, later I find out, on this forum, that TJ offers custom cables and he's in the US so I'm probably gonna use his services in the future. His website says he backed up right now.
