Congrats on the new machine. At that price, there really is no competition. There seem to still be a few teething problems with the EM6900, but Sunbeam are pretty keen to sort these out and will fully support their warranty. I think it great to see an Australian company who are trying to make quality espresso machines for the domestic market. Of course the machines are actually made in China, but soon everything will be made in China.
However, I reckon you should put the money you saved into a better grinder. This is the most common piece of advise given and for good reason. The grinder is at least as important as the machine. Just because a grinder can choke a machine doesnt mean the quality of the grinds are top notch. I can choke my machines with a wirly blade grinder. The quality and consistency of your shots will only improve when you use a decent grinder.
BTW: If you want a local Brisbane company to deal with, that sells a wide range of grinders, try Barazi. They are excellent to deal with, and sell a wide range of grinders, from Rocky (not my favorite) to Mazzer and Bezzera. They have a great deal on Mazzer Minis at the moment, so its worth a call.
