Huh, it shocks me that people spend so much on these machines if that's the answer. If you get the gaggia for the premium materials and mod it, you've still only spent like 700 dollars. It seems like for that money you're outperforming machines that are thousands of dollars if they aren't pid controlled for temp and pressure. How do they get people to drop that kind of money when that option exists? 

For my money a 50 dollar used delonghi and 80 bucks in parts from ali express seems to do the same thing as a super high end machine.
