Last month I got a simple pour over setup that's not full-hipster. Coffee is 10x better than a Keurig or instant coffee. Both of which i have. Maybe it's partially being trapped in house but it's bordering on better than the coffee shops nearby.
I dare say that if you are capable of following instructions, and have $15 to invest into a freshly roasted bag of beans from a coffee shop, then your coffee is exactly the same quality as to what you would get from a high end coffee shop. The only difference is that the coffee shop will charge you up to 5 dollars for a fancy pourover, while your 15 dollar bag of beans will last you several weeks.
Having a water cooker that is accurate up to the degree is essential too. I'm experimenting with different temperatures and it's a huge difference. Some coffee is nicer at 91c, some of it is better at 93c.
Setup:
Hario v60 ~ $20
Pour Over Filter ~ $10
Grinder - $30 (already had)
Kitchen Scale - $10 (already had)
