Nick,
You might consider a MyPressi Twist as a backup. It's espresso only, no milk frother, and it uses gas canisters, but the price is right and it makes good espresso with 18 grams of coffee. You could use your La Pav for texturing milk. I outfitted a
travel case for mine, though it spends most of it's time at work for the afternoon double. You could use it at work or when traveling and bring it home when entertaining.
There's rumors that they're working on a hybrid gas / rechargeable electric version for times when you don't want to use the cartridge or when it's inconvenient (since there's travel restrictions on flying with the cartridges), but I don't see that up on the site yet.
