Gieseler Audio USB Reingen
Seen a photo of a fragment of PCB. It looks transparent - two sides only without a solid ground plane between. It is acceptable for $50 product. Even the model you found for $80 had four layers board.

This is the ADuM4166 USB isolator/regenerator @sajunky refers. It looks well designed and built for USD69 and provides for an external DC power supply.

This is a lowest price I saw!

There is a new isolator in a smaller package, but PCB seems to built on the same concept. It has USB type C input, it is not what I do prefer, but convenient for Macbooks and ultra slim notebooks users. Only $27 which is surprising given what is inside. Posted already on the U2 Poorman DDC thread.

Note of number protection components (which are not cheap) like TVS diodes and polyswitch type overcurrent fuses. A new link $26.

You are always naynay. :)

A product is selling for one month or two and has no negative feedback.
I'm not saying these products don't do a good job price to performance, just not for me to much uncertainty.
