In case you havnt read it yet look here http://coffeesnobs.com.au/YaBB.pl?num=1241050011/0 also first things first lose the pressurised baskets in your bottom drawer and use the proper non pressurised ones and a decent tamper if you didnt get one with the machine to start with.
Most important thing is get some fresh beans !!!! Stupormarket is not fresh so chase up your local coffee roaster or one of the sponsors here.
Have fun playing :)
