This system is a great entry point to all-grain home brewing, making batches up to 20-30L depending on style.
IMHO, it is exceptional value compared to other single vessel systems such as the Guten 40L Brewery System ($475), BrewZilla 35L - Gen 4 ($605) or the Grainfather ($1000-$1185).
If you want to brew even more beer (up to 40L), this Grainfather S40 Brewing System looks to be good value too ($420 plus postage, normally $725) https://www.kegking.com.au/grainfather-s40.html.
Shout out to Chrool in comments - BrewZilla 65L - Gen.3.1.1 ($480, normally $619) - note that this needs a 15A supply for full heating power

Be aware that these guys are short staffed, and it's taking them a week or so to even ship things.
They don't tell you this until after you've ordered, even though it seems to have been going on for months.
