I second the suggestion of a Nespresso machine.
I think we paid euro100 for one in Europe about a year ago, and it came with a carton of 250 sample capsules (maybe 12 different blends, with descriptions, tasting notes, and so on, which made trying each blend more interesting).
There are mornings I might have perhaps 3 cups, and other weeks I'll stick to tea. Either way we still have half the capsules still to go.
I've narrowed down my favourites to 2 blends, and my wife is going to pick some up when she's soon over in Europe. IIRC over-the-counter a box of 10 capsules of your specific choice of blend is about euro6.50 = S$1.10 per coffee.
p.s. I was looking at reusing the capsules , or buying a custom made reusable pod (refer videos on Youtube demonstrating both!). But my wife accused me of being cheap
