I just reread your post. At first I thought you were just looking for a machine recommendation. I think the most important things are that the coffee beans need to be good and well roasted, they need to be fresh and you need to have your ratios right. I have a pretty cheap, hand-me-down coffee pot but with the right beans and ratios is makes fabulous coffee.
I like to buy my beans whole and grind my coffee at the store (my inexpensive coffee grinder always leaves it tasting a little scorched). Then I squeeze all the air out of the bag, close it and store it inside a large ziplock bag in the cupboard (away from light and heat). I brew only for myself and a pound bag stays fresh long enough for me to use it up this way. Don't put it in the fridge or freezer.
I like Starbucks (don't tell the lady I work for!) Sumatra when I'm brewing at home. Experiment and figure out what bean and roast you like. I like low acidity, full bodied coffees myself. Papua New Guineas (last year was not a good crop for them though) are another of my favorites. Not all roasters are created equal. Some brands I don't like their Sumatra, others I do. Experiment in small batches and figure out what you like.
The Starbucks bag recommends two tablespoons
I think of grounds per cup (maybe I read that wrong?), I use about a tablespoon per cup. Consistent measuring is important and then you can adjust up or down to your taste. Good water is important too. If you filter your water to drink it, use filtered water to brew your coffee.
The Keurig K-cup coffee makers are beloved by a lot of people who only brew a couple of cups of coffee a day. The coffee is measured and sealed in little K-cups that you put in the machine and push a button to brew. They are clean, neat and consistent but the K-cups are a little pricey in the long term. I bought one for a friend and he loves it. I am almost tempted to get one but go through too much coffee for that to be reasonable for me. I also like the option of trying new coffees that I see at the store.
I like to think the coffee I make at home is better than a lot of what you find in cafes
