Take a look "1st-line equipment" here:
Espresso Machines, Espresso Coffee Makers, Coffee Roasters and Grinders. They have a bunch + good info on each. I have bought grinders, espresso machines and drip coffee pots from these folks. They have very competitive pricing and are great to do business with! I have no connection with the company; just a happy customer.
Coffee is my "other" hobby. I roast my own and have several grinders. Suggestion: "Don't go cheap!" Those little handheld grinders are crapola/junk. But then you probably already know that!
