If anyone is looking for replacement cables, I can confirm that 0.78mm pin cables on aliexpress work fine. The ones I got were "6N 0.78mm 2 Pin for Weston TFZ" for around $11. The cable is a bit shorter than the default ones, and the metal pins stick out by like 1mm, but it's overall a good fit.
divinebaboonMy old aliexpress ones broke after i yanked them too hard, got another pair of replacement cables from ali for $5, search "TRN 0.78mm cable", fits great, no metal pins sticking out this time.
