Nespresso (Nestlé) - Lattissima+ (f 411, f 416, f 421, EN520W, EN520R, EN520S, etc.)

Get both systems if you can manage it. I love my OL Lattissima+ with integrated milk option and my VL Roundhead machine for coffees. And I have a Pixie at my office.

if you want flat blacks then the vertuo is good option as the machine is cheaper, but you are limited to buying the pods from nespresso and they are more exepensive than the original line (OL). OL line is better for espresso and milk ones - and can do a decent job with flat black (with some trial and error) - the pods are cheaper than the vertuo pods at nespresso and you can get a host of even cheaper 3rd party options (local stores - country/state dependant or via online like amazon etc) - though the cons are the machines are more expensive. If you are going for a citiz or pixie (OL) or similar I think you are hitting the sweet spot. If you are going for a more costly machine like the latissimo or sage then you might want to consider/look at decent bean to cup model as they are in similar price range and while not quite as convient and take larger space you technically can get a cheaper cup from them.

I think switching to a Nespresso OriginalLine would be much better coffee than drip, since it makes espresso shots without any extra work.
