Turin - Gallatin V HX Espresso Machine with PID (G3035)

Heat exchanger machines are cheaper than double boilers but, unlike single boiler machines, they allow you to pull shots and steam milk back to back without waiting. The one thing to know is that you really want a PID on that heat exchanger or else the heat will be all over the place. I was recently in the same place you are and I bought a turin Gallatin. So far, I’m extremely happy. It’s beautiful, it’s very functional, and I got a little joy out of it every morning. No regrets. It takes about 20 minutes to warm up. Oh, and I upgraded from a rancillio Silvia with a PID. I love that workhorse, but it requires a masters degree to pull consistent shots, and there is a wait time inherent between switching from pulling a shot to steaming milk.

Nothing...you can literally achieve the same results on any espresso machine that does 15 bar, which is almost all of them. You change the makeup of your shot based on grind level. Get the new Bookoo Motto80 grinder. It's as good as the current $3000 grinders but will only cost like $1000. You can't go wrong with the Motto 80. If you really care about having a shiny looking machine, there's plenty of options like the Turin Gallatin but you could have everything needed in an espresso machine with the Turin Legato v2 which gives you full control over flow, pressure and temperature. It also does pre infusion.
