BIG difference between home/commercial machines is consistency when extracting/steaming back/back for multiple drinks. You're not really paying a high price for great espresso capability, but more for the build quality/longevity.
If you're using the cartridges commonly used for whipped cream they are NITROUS OXIDE (food grade), not to be confused with CO2. When buying in bulk (96 or more) they can be found for .50 each or less.
Yeah, that's what the cost off of e-bay and that is what I use. I'm not confused between N2O and CO2, you can use EITHER gas as long as it's the 8g "food grade" type. The 8g CO2's are "seltzer bottle" chargers and are no cheaper than the N2O of e-bay.
As for back to backs... yeah, I do that all of the time. I can get six double off the cartridges now that I disassembled all of the o-rings and oiled them all with Canola Oil... if I don't let the thing set overnight or longer. So when I use it, I pull off all six back to back. As long as I heat the shots the same, dose and tamp the same and grind the same, all six come off exactly the same.
So it can also do consistent shots.
My wife declared that she likes "Moka Pot" and doesn't like the MyPressi Espresso. So, I'm glad I did that and not the Silvia. It appears that I will only be using it 1-2 a week now as a compromise.
You have to also realize that I can buy 7 MyPressis for the price of a Silvia and 20 for the cost of a good HX machine. It does have it's place.
