Joystick cables with molded DE-9S connector?

Hi,

After a long break, I fired up my Vic-20, sd2iec and UltiMem. Great 
stuff, but all of my joysticks suffer from worn cables. It is not fun to 
play games if the joystick movements are only intermittent.

A few years ago when I was searching for joystick cables with a molded 
plastic connector, I found nothing. Today I found one promising shop, 
but still sadly nothing in the European Union.

I also found some related forum discussion. The first one is about 
joystick cord extension and building a buffer to protect the CIA or VIA 
when using a very long joystick cable:

But, I fear that a metal connector case could scratch the metal shield 
around the joystick connector. Here, someone came up with a DIY solution 
of removing the metal part of a DE-9S connector, adding a circuit board 
and applying heat-shrink tube:

On that forum, some people are also questioning the quality of some 
joystick replacement cables. I would guess that some of them could 
originate from used joysticks, or be old stock from decades ago, and 
thus be prone to failure.

This Australian shop claims to have newly produced, 9-pin cables:

(As you may know, the +5V signal was often omitted, and the paddle 
signals were almost always omitted, so most original cables would be 
only 5-pin or 6-pin.)

I found also this shop in the United States:

Does anyone have experience with such replacement joystick cables?

Last, thinking aloud, are there adapters that would convert modern USB 
or Bluetooth controllers to the Atari 2600 format? If not, maybe that 
would be a fun project for me. That would be a small box that would be 
powered from one joystick port, optionally with additional cables to 
other joystick ports. Somewhat related to that, one could want to equip 
and old joystick with a small battery-powered Bluetooth microcontroller, 
for a wireless playing experience.

Best regards,
