My espresso machine nearly 10 years ago. I think it was nearly $500.
I made drip at home and purchased lattes on the road. I bought the machine to make them myself in the morning and load up a tumbler with essentially 2 large lattes.
It definitely paid for itself within 2 years and I switched to work from home so I'm glad I have it today.
Besides using only distilled water in it I do basic maintenance of running coffee cleaner through it every 3 months or so. Never had a issue with it and it still works great.
Best purchase ever. Only downside is I make better "coffee" than most carry out places. I hunt for good coffee when I'm out. Found two shops locally that make great espresso drinks and pastries. I go a few times a year.
Good coffee is a dark black hole to get sucked into.
