While those machines seem practical, being limited to only their capsules may not be the perfect solution.
The moment I started paying attention to my coffee I have stopped drinking coffee from a Nespresso machine at work - my electric moka pot was giving me better results.
While I support recommendation for E61 HX machines, the setup with a grinder will be more of $1800 range. For a start, I would recommend looking at the New Baby Twin from Gaggia that has dual heating system for simultaneous steam for milk and water for coffee. Paired with a decent grinder (such as Rancilio Rocky) it may provide a great setup.
