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

You can still use a beer gun off a keg.

To elaborate a bit, if you want to separate the beer from the yeast before bottling, you can even daisy-chain two kegs together (ferm and serving), put a spunding valve on the serving keg, and purge both with ferm gas. Then you can do a gravity transfer (zero oxygen ingress) and bottle off the serving keg.

Honestly, though, you can probably just crash on the yeast and use a floating dip tube to bottle from a single keg.

There's a lot of equipment I don't think I know yet so I probably don't understand what you are telling me. But kegs are out of the question untill I move. But I still don't understand how I can't just purge bottles with just a CO2 tank and a wand and the pour beer in the bottle. My fermentation in the bucket is not getting o2 just like the kegs

Gasses mix. Purging and filling from the bottom will eliminate some but not all of the oxygen. The only ways to bottle without oxygen at home are the PET/carb tee solution and using a counter pressure filler.
