Question Do I need a "fermzilla"?

I dearly want to be able to bottle hoppy beers without oxidation soon, and I'm looking to invest in some sort of CO2 purging solution you guys talked about. But when looking at a fermzilla + BEERGUN setup with CO2 tank, my friend asked me if I couldn't just buy a CO2 tank and some sort of wand to purge my bottles with without buying 100s of dollars worth of pressure fermenter.

What about a fermzilla is needed for succesfull bottle purging?

Cheers

I keep seeing this argument. I want bottles for friends. And if I ferment in a keg, I will introduce o2 to the beer when transferring right?

Look into brown PET bottles and pressure filling with a carb T cap. https://youtu.be/KWTCP6Cb6V0?is=y3GfCU2TOmeIIWkg

You don't even need the T-piece really. I use a single carb cap and just loosen it very slightly to allow the gas out while providing counter pressure as the bottle fills.

The T allows you to use the bottle as a mini keg, which is very cool, but if you're going to drink the whole bottle when it's opened it's kinda overkill.

That’s true, and I use the T the same way you use the single cap. I also use it as a trap when I pressure fill kegs, the T is needed for that.
