No, I don’t think so. While his listed prices are extravagant, I see it as more representative of the huge cash outlay others prescribe as what should be bought.
As an example and not picking on the fella is AJ. He is super pro GV-OD. Is it really needed?!?!?! Not in my world. AJ thinks the world of it and a worthy expenditure, as well as many others. All in all, it’s the end users choice. I just do not deem a GV-OD necessary.
