GO

Built in PID. Temp gauge. Adjustable pressure. Profitec Go had all of these and I love it.

Profitec GO. Real espresso and built rock solid.

I have a profetic go and it only takes like 8 min to heat up then u flush it to temp. It's really never been a limiting factor for when I want coffee. If u want to have it ready in the am just get a smart plug and set it to start 30 prior to coffee time. You are correct with a heat exchange you will need to spend 2-3k on a good one and they are also power hogs at 20 amps in the USA.

I think the only reasonable upgrade is a Gaggia Classic EVO PRO or if you can find a used profitec go. Just be aware that you’ll most likely need a bunch of new accessories since these are 58mm compared to 54mm. If you’re happy with the bambino plus and had no complaints then get a new bambino plus since it’s on sale right now.

Had the gaggia and switched to Go last Christmas.. If the budget permits, go for profitec. I like the PID control for consistency

I recently upgraded from a Profitec GO to a Linea Micra, and couldn't be happier. The single boiler workflow was getting very annoying, even with the GO being quick. I got the Micra for $5600 CAD. It's expensive, but I'm sure it's going to last a very long time. They don't offer any flow control, which is not an issue for me since I was looking for an easy workflow that produces good coffee. The Micra delivers that for sure.

I wouldn’t get this machine or breville/sage machines. I had sage barista pro and it’s group head leaked water, apparently its screws lose and I opened it up put some lock tide, it worked for a while but it did it again, I sold it for a very low price just to get rid of it. It is an appliance not a machine, it will break eventually. I got a Profitec Jump amd Eureka perfetto grinder, it was sold as a pair with discount. I realized the how high quality can a machine could be. For a lower price, I would get Profited Go and a eureka grinder (or other decent grinder) usually it is sold as paired with a nice discount. You would thank me later.
