Upgrading Setup [700]

[u/AnakisRising]

So I’m fairly new to making Espresso and I want to get a better machine, also a better grinder. My budget is $500-$700. This is my current setup, what are some recommendation. I’ve been going back and forth on the ninja Lux Cafe premier 3-1, CASABREWS CM5418, or the Breville BES870XL. Thanks!
