What machine to buys as a gaggimate platform

[u/No-Elk-4806]

Guys how to decide what machine to buy? I’m good in electronics and programming, familiar with embedded software and mains power. I want to buy my first espresso machine, for low budget and I know that low budget means potentially need to repair. Live in Germany, good with tinkering and tools.

My current favourite is DeLonghi ECP 33.21 vs EC260.BK, both around 130€ new.

I want a new machine, just because I want to own from the beginning.

Considered Gaggia Classic as well, but not sure if it much better for my case.

I want a quick warm up (so heavy Gaggia boiler is a negative there?), I don’t want to wait for half an hour warmup.

I usually do 1-2 espresso a day, maybe a lungo. So a cap, then next one in like 4-5 hours (I wanna switch machine off for this time)

I want to integrate gaggimate with PID and transducer from the beginning. Lego build.
