I thought I saw on here that it was recommended to get a 53mm tamper for this machine. I just received my RW aluminum in the mail today and it's just a tad bit too big for the basket on this machine and does not seem like it will get a good tamp. I read today on another blog that it should be a 49mm one. Thoughts on this?
my apologies for the confusion! The portafilter on the EC270 is a 49mm.
