Hello everyone. I've scoured these forums' mypressi threads and have been unable to find any information on cartridge replacements and where to get them (on the cheap). I notice that the size differences in cartridge brands seems to have been taken care of, but don't know if there are some brands that still don't work. I also can't figure out if "12-gram" cartridges will work or if they still need to be "8-gram". So, anyway, those with a Mypressi Twist: from where do you get your replacement CO2/N2O cartridges? And what brand/gram have you found to be cheapest? Thanks so much for the help.
