Dont know? it's 4 months old and owes me $200 and it would cost $250 to $280 for one landed it now. So basicly in a nut shell I dont know. lol. It would be marginal to get a 10 gal one in at the moment for under GST payment. ( anything GST claim under $40 dollars they wont make you pay but thats car parts?)
For a False bottom its 38.95us plus 37.95us for weldless coupler and ball valve and another 3.95 for threaded barb each! that would enable you to connect false bottem to bulkhead fitting, plus say 30 shipping makes it 114.8us so about 195 kiwi plus 160 kiwi for the Cooler from Payless makes it 355 NZD. Is the Forty dollars worth the hassle of trying to source all that parts and bits from all over the world and NZ?
I can cofirm they are great. Excellent heat retention and the false bottom works like a charm. Sparge arm isn't a must but I'd rather have it for sure.
I never contemplated 5 gallon. Time is my biggest hinderance, so I may as well always brew as much as I can at once.
