Retail ricing on Entreq grounding system

There have been a lot of discussions about both Entreg and Tripoint Troy grounding systems.
I know Tripoint is FAR more expensive, but I couldn't find any references to an exact pricing of Entreq system.
(As a side note, It's always been very irritating to me,that manufacturers do not publish pricing of the website???
Are they trying to keep pricing secret from potential customers? Imagine going to ANY retail store with no pricing labels on anything).
Can somebody post retail price of the Entreq system, please?
I contacted Entreq direct for the price. I believe they offer a money back guarantee. I plan to try one soon.

Whoever you are buying from, make sure he sells you the latest ‘Infinity Line Tech’ upgraded ground boxes and cables. Most of the US retailer are still trying to offload ‘old’ incentory and have not posted pictures of the latest Infinity Line. I spoke with the Canadian distributor at AXPONA and he mentioned new improved line is much better.
