Anyone Here Using a Bialetti?

I lived in Europe with some Italian guys and they would always share their coffee with me. I came to love it and I really want to make my own. They used a little Bialetti and some brand of pre-ground espresso. If you use one of these moka pots, what coffee do you buy and where do you get it?

I've seen several brands of espresso but I'd like to know what you prefer in the moka.

Thanks for your responses
