I just bought a fabulous Jura espresso machine and I know nothing about espresso beans. I really need some frank advice from my fellow Chowhounders. Please educate me. I want to learn, but if it makes it easier, please just tell me which brands to buy and where I can find them at the best price in the GTA. I can live without going to Pusateri's ($$) for this purchase.
p.s. fyi. fresh key limes at T&T Cherry Street for $2.49 a bag.
