One has to decide certain attributes / characteristics that are wanted for the 2nd location.
You mentioned a couple such as 'theft' and portability.
For me the 2nd location I'm planning for is the office.
I wanted a 'stealthy' setup. One that doesn't make a lot noise - my initial machine was an Estro Vapore i bought from Starbucks - definitely not a quiet one. I bought an NS Oscar since I wanted more oopmh and the price was right (<<50% off). Unfortunately it also was loud due to its vibe pump. So, i opted for a manual lever, waited / stalked eBay and got a Europiccola. I would've preferred a Cremina or Elektra leva

but one does what they can with resources available.
In terms of grinder - since I wanted a stealthy setup - it became a manual old-fashioned hand grinder - PeDe Mokka.
For all intents and purposes this combo was meant for the office. But... now I find I enjoy it so much on the weekends I don't think I can part with it. Plus I still haven't quite gotten the PeDe dialed in for the europiccola.
Hmmmm...... maybe I need to do some more stalking for that Cremina / Elektra Leva?
