>At $3/coffee (black, nothing fancy) purchased on average four times per week across 4.5 years of school, the total came to roughly $1,700

$3 x 2 people x 365 days = ~$2K

A decent fully automatic Espresso machine is ~$1K. You load the beans once per week, water every day, and run the descaling cycle once every few months. And these things are modular as hell: if you are not intimidated by reading a service manual and know how to get around with a multimeter, you can get replacement parts from specialty shops and maintain them yourself at reasonable cost.

And the best thing is, you don't need to go anywhere. You wake up, crawl to the kitchen, press the button and enjoy the coffee.
