and I completly agree. It takes me 20 Min. to machine the parts from scratch, but given my hourly rate it's cheaper for me to source the Mazzei Injectors, and modify the gas intake. This becomes more critical for folks using yeast reactors, and only increases the efficiency of tanked gas. It also becomes increasingly important for low pressure "Powerhead" systems. Not everyone wants the expense of tanked Co2 or expensive pumps, and not everyone wants a reactor in their system. Yet the cost of an improved venturi is just slightly higher than a ceramic diffuser, and they have lower maintenance. Savvy ?

Face it. Once you've shelled out for tanked gas a $25.00 injector becomes rather trivial bye comparrison. So If others can benefit from the same system without the expense, Good For Them !

For the Record I'm retired. I don't make one red cent off of this The process has cost me time and money. That's why I won't post pics to the web. Many fine contributors of this forum have done that in the past only to have someone pirate the very design they provided the community for free. Put it into production, and sell it retail. The punch line gets even better when folks purchase the product, and come right back here for advice, only to gripe about a membership fee ??? Just Imagine The Irony ;^))))) BWAHhahahahhahahhahha.
