I got a basic morphy richards espresso machine for about 3.5k, it also has milk frother
Espresso machine is quite useful and multipurpose, you can make concentrated espresso shots and literally make anything with it, hot or cold.
add frothed milk in it and you have cappuccino, add ice and water to make iced americano(add milk and sugar to taste).
mix it in a blender with ice, milk and sugar to have cold coffee.
definitely takes while to get the hang of it. grind size, brew time, freshness of shots makes a huge difference in the taste of the coffee but its really fun and you can customize it however you like, you can experiment with various things to see what you like the best.
The taste of freshly brewed coffee is on another level compared to instant coffee, after few trials i AM able to make americano which is almost indistinguishable from starbucks one in taste as well as in aroma.
