They seem to be impossible to find these days.  I've had a running search on eBay for years for anything from Quantum Products, and never had any results.  I can only conclude that very few of these things were ever made.  As even with Springlife Polarizers, you see these come up in estate sales (people may not want to sell them, but eventually they do die).

Also, over the years, the Quantum Pro changed in strength, so the newer ones are like 4 times stronger than the older ones.

I believe the closest thing to these on the market today are the Symphony by ADD-Powr.

I suppose you could try to contact the company that made the Quantum Pro to see if they have any residual unsold stock.  As they still have a website, just nothing advertised for sale.
