The problem with espresso grinder is that they are a pain to use for anything else. Even with my setup with the Baratza Vario which easily switches grind size I like two grinders. A good burr grinder like a refurb or new Baratza Maestro will compliment your TV and other brew needs well.

When you plan on getting an espresso machine? Start gathering info now and plan on getting over loaded with info that tries to separate one hot water delivery system from another. You have the most important pieces already, the grinder and you.
