Prices for coffee machines at Keurig are lower than those of Nespresso for the Origin line and Vertuo line.
Keurig starts with $$, then Nespresso is closer to $$$ and Vertuo is always not less then $$$.
The range both of producers is very wide, and it will not be difficult to choose the model that you like.
As it turned out earlier, the pods for Keurig are also cheaper, so it is very easy to choose a winner in this category.
