I have a refillable. PITA to clean. If you are going to do that, might as well just get a small brewer. which I may do next time I need a new one. I have a French press If I feel like cleaning up the grounds after using it. I've also used the 'fill your own' disposable cups. If you want to use better coffee, they might be cheaper. But Ive found enough cups on sale that are OK, so not worth the effort to me.
