I have about nine coffee makers
One huge (stainless) 60 cup perc (makes GREAT coffee, BTW), a 4 cup Mr. Coffee, a 12 cup Mr. Coffee, 1st-2nd-3rd gen Grind 'n Brews, Mr. Coffee pump espresso, Krups pump espresso, and a Melita "Two to Go" drip machine.
Most of these are in storage, save for the Melitta (which I use occasionally to make tea) and one of the Grind 'n Brews. Oh, and also have a manual Melita cone and glass carafe setup that is my Mom's, which cleaned up very nicely in the dishwasher, but I've yet to take the time to brew a small pot with it.
If I want strong coffee, I'll make espresso. But usually I would use the espresso to make a low foam layered latte - my own special technique for which one must heat/foam the milk first, with sugar if desired. Then layer on the espresso and the more dense coffee sinks to the bottom, looking very fetching in a glass mug. The trick was finding an espresso machine that was tall enough to allow the glass mug to receive the espresso directly.
Currently not drinking ANY coffee. But with the 3rd gen Grind 'n Brew, I'll proabably start up again. Although one of those pod affairs would probably be most appropriate for my level of consumption. I just like the gadgetry in various types of coffee makers. I also have about three different burr grinders...
I agree that fresh water from the cold tap is a must. Perhaps one can't tell as readily with coffee, but for tea any water that has been kept heated for a while gives the tea a very flat, "cooked" taste. It's lost its air and isn't far from hot tap water. One reason why I've avoided the Bunn and its clones. The other reason is the energy required to keep that water at brewing temp 7x24.
I happen to like the lighter roasts as well, at least for drip coffee. One of my favorites used to be Guatemalan, but haven't found any in the past few years that was as good as the stuff I used to get in the 70's. A darker roast is good for espresso. But I'm not too fond of the very dark roast that Peet's and Starbucks use. Too bitter.
