My take is invest in something of quality if you enjoy it often. A thing of beauty, etc.
The coffee in Switzerland is generally of very good quality, even dare I say it supermarket own brands. There are many places where they roast coffee; try asking in a Cafe or even bakery where you like to drink as they often sell what they serve. I don't know about your neck of the woods but in Zurich we're spoilt for choice. Freshly roasted is the important bit.
Forgive me for mentioning it but there's a world of taste difference between freshly roasted and ground, good quality coffee and the stuff in a capsule / pod. Nespresso and their ilk have excellent quality control and make coffee 'easy' for those not too bothered about the taste but it's rather
meh. It's the pinacle of Monoculture and lacks soul. If you take sensual pleasure in the things you eat / taste...
If this isn't of interest and the financial element doesn't matter, take the easy route and buy the aluminum capsule / pod device. As with printers and their cartridges, they'll give you a cheap machine and screw you with the price of supply. If you're undecided and are considering a 'real' machine, a decent place will allow sampling of their machines; 45 minutes well spent
Below is where I get my
fix supply, where they also do decaf (
