The Gaggia Classic Pro is a popular machine for people who want to modify them. But Gaggia says that it's not necessary. We disagree and talk about the simple job of changing the OPV spring on the Pro.  

We have to mention the new Victoria Arduino Eagle One Prima, which has got Max very excited - but how much will he have to pay to get one!  Finally, we talk about the Bean blending challenge with Carvetii Coffee - more on that next week.
