Robobrew is good, delighted with mine. Any brewer who frowns upon an all in one vessel is a fool. I'm absolutely more than capable of using a 3V system, sadly I don't have the space nor the need. It actually wouldn't be any cheaper for me to build/buy as good a quality 3V system. Stainless ofc. I never set out to buy an all in one vessel to make good beer for me, and glad at that because it doesn't happen. But I did end up with an all in one unit as I realised BIAB was perfect for my needs, ruled out 3V brewing as the small scale made it pointless - therefore eRIMS/eBIAB was the next logical step.
