Seems as if there are precisely zero online retailers that have Gold HS Filter'Trons available. I'm looking to upgrade the Blacktops in my G5422TG, but I don't really wanna spend $140+ per pickup for TV Joneses, even though I'm likely going to buy one of their wiring harnesses. Are the TV Jones offerings really $100ish better for a set? I know that's a loaded question lol. TIA!
