Lance Hedrick in his latest video (review of Decent XL) mentions that he got the Gaggiuino parts, but haven't got around to building it. I look forward to that video, whenever it comes out.
Yeah, I’m looking forward to his experience. I’ve been on the fence about whether to build a Gaggiuino myself, or sell the GCP and upgrade to a dual boiler machine. I don’t really care for flow profiling, but more stable temps and auto shot timing would be nice to have. And I make a lot of milk drinks so a DB would eliminate some of the wait time and need to flush the boiler.
