Have Keurig machines at work. The coffee is good enough to drink at work but I'm not buying a machine for the house. I don't want Blueberry coffee...
You don't want to make 10 oz with one container since the same amount of grounds for 4 or 6 is going to be too weak with 10 oz running through it (unless you prefer "Passover Coffee"). That said, you can run two cups at 6 oz each to get a good and strong twelve...
If you can taste the difference, go with Mr Coffee style machines that brew one cup. Buy a week's worth of whole bean and grind them at the store and seal them in an air tight canister. I think that would suit your purposes better.
I've found the perfect bean, grind, and amount of water combo to suit my taste. It's easy enough to do regularly and get exactly what I want.
