How difficult and/or rewarding is roasting your own coffee beans?

Question

I've seen green beans on sale, are they worth the bother?

Answer 1

My co-worker roasted her own beans using a popcorn popper (a google search will get you directions) and it was THE BEST coffee I ever had!!  You don't need creamer or sugar or anything because the coffee is the BEST.

Answer 2

It is my understanding that to do it well is quite difficult.  You can obtain excellent coffee just by grinding your own roasted beans just before you brew a pot of coffee.
