I have around $1000 in a decent espresso machine, 2 burr grinders (1 for regular and 1 for decaf), and a milk heating/frothing appliance. I’ve had it all for over 10 years, make a couple lattes a day typically (one for me, one for the wife). Let’s say 2/day x 250 days/year x $4 each at *$$ => $2000 per year saved, minus milk and coffee costs, which are pretty minimal all in all. Plus I don’t have to go to *$$ and wait in line.
My espresso maker is. 40$. Lasts about 3-5 yrs
Makes 2 shots then have to cool and refill h20
