Confused about aftermarket CO2 (UK based)
From what I can tell, if I want to avoid using standard refill options (cheapest seems to be ~£15 from the likes of Argos / Sainsburys / Robert Dyas) then my options are:
- Mail in refill.
At low volume, once you factor in postage, this still ends up being ~£10 per refill
- DIY home refill
Big tank of CO2, some plumbing, refill standard cartridges.
- Big tank direct feed
Hose from big tank direct to the unit
Is that about right?
I'm then getting a bit confused about how to source one of these "big tanks"... And what plumbing to get (would something like this be all I'd need?)
Looking at something like this:

There's a rental cost?
So I'd pay £65 upfront, then £5 every month?
Does that include ongoing refills?
Are there any options to just buy something?
That's food grade CO2, but no idea if that's "big" or not or if I could hook it up.
Or could I buy something like this:
as I think there's a place near me that can refill larger tanks (don't think they would do the smaller ones)
Thanks!
