I have an AllClad "Presso" espresso press for making the strong stuff. It makes an astoundingly smooth and strong cup of espresso. Of course, it's a manual press, and therefore, you have to actually use your hands to use it, and it has a slight "learning curve"--pull the levers down too fast and you squirt liquid out the sides, bring them down too slowly, and the coffee looses some of it's "punch", but it's well worth it, IMO...
For a regular cup of joe, there are only two ways to do it. Forget ANYTHING that plugs into the wall.
If you want the smoothest coffee you've ever had, with an espresso-like caffeine level, cold-infusion is the only way to go. You just fill a container with cool water, dump an appropriate amount of ground coffee into it (usually about 125%-150% what you'd use for the same amount of water in an electric coffee maker) put a lid on it, and let it sit overnight. Then you strain the grounds out the next day, and heat the liquid in a pan or percolator, or for a REAL treat, use it to make a FANTASTIC jug of iced coffee. You can use a french press for this, but I've actually had better results with a big bowl, and then strain it with a funnel and one of those reusable gold-screened coffee filters.
If you don't have the time (or the desire to be that involved with your joe-juice) then a French Press kicks the butt of ANYTHING that plugs into a wall, as far as smoothness goes. In less time than an electric machine takes to make a batch of coffee, a French Press will turn out a velvety-smooth, mildly acidic batch, and the "press" part keeps all the grounds out without having to mess with disposable filters. Plus, since the entire device is re-usable, it's a VERY "green" way to make coffee, because the only energy used is to boil the water you pour into the press. I have several french presses, ranging from a small 2-cup press I use when camping, to a big 12-cup press I use when we have guests at home.
And of course, traditional Ethiopian coffee (Bunna) is a real treat too, and is equally low-tech. It's a boiled style (sort of like traditional Turkish coffee), where water is brought to a near boil in a large ceramic pot, then the finely ground coffee (which was freshly roasted and ground, right before) is dumped into the water, and steeped for a time. Talk about a cup of coffee with a unique taste, aroma, and jolt! Woof. My favorite part of going to the Ethiopian restaurants in the DC area was on Sunday afternoons they had Bunna ceremony. The whole place smelled like roasting coffee beans, and the little cups at the end of the meal were always the perfect ending to an already fantastic meal...

What it really all boils down to is that if you are spending more than about $100 on a coffee-making device, you are paying for convenience, gee-whiz "features", and "bragging rights", NOT a better-quality cup. The BEST coffee and espresso come from ancient, low-tech, hands-on approaches, and require an amount of special knowledge, timing, and intimate knowledge of the ingredients.
Coffee, like ANYTHING worth doing, requires active involvement if you're going to get that extra 5%. You can throw all the money in the world at the process, and get a pretty good result, but if you want to achieve "nirvana", you gotta spend some time, and get your hands dirty...
