a PID is the minimum barrier to entry for eliminating machine-variance in shots. with a PID single boiler dual use machine + a good grinder, you should (in theory) be able to do consistent, cafe-quality espresso. without a PID you are relying on the machine's thermostat, which will vary from way too cold to way too hot.
if you're looking at the lelit anna, i'd still consider climberevan's machine. or, for the same price, look at this guy:
