Hello Xian,
I know this is from ending March but... did you manage to get any? I might have one I can send you for free, have to look for it thou but I am pretty sure I still have it.
Same here as Ren-chan.
However, it no longer has the cord and a solder pad is broken on the PCB. Can be difficult to repair. I kept it for spares, but still free for you James.
