Have found around funky blog about espresso coffee named "Espressoguy.com".
It's full of cool facts about the product and also there is a lot of servicing tips about small espresso machines.
Personally I'd found useful the next article about the machines cleaning and hope it helps somebody else
I have read the post you have referred in this post. I really liked it. Is there any website for the coffee machine reviews? I need to buy an espresso machine and looking for some help.
