“Low cost” is relative. For parts in the industrial/robotics space, $195 is not expensive.

You can certainly spend more on other options: https://westwardsales.com/patton-cl2300e-ethernet-extender

You can get full products that do higher speeds over longer distances at lower cost, search term "vdsl repeater".

It's possible that this product handles bad wiring better as it's ethernet rather than VDSL2, but I think those devices are a much better fit.

One thing that might be better with an ethernet based standard is the ability to add multiple stations to the same link, relying on ethernet's error correction.
