I use RO water when I make coffee.
I too am tired of buying consumer kitchen stuff that has a life span equal to a pair of jeans.
Presently I have a Cuisinart Thermal Carafe unit and it's been around for almost 11 years. I like the thermal carafe much more than the standard glass carafe, the maker makes coffee and it's off. I also have a Barista (from Starbucks) espresso maker which has been flawless and it's about 7 or 8 years old. On sale it was $400 but it makes great capuccinos and my wife says that its worth it to her (that I get a serious cafine shot that is).
I use a KitchenAid burr grinder for all of my coffee, its the one that looks like a bubble gum machine. I've had to re-work the motor mounting screws after it all came loose and the warranty repair shop did a bad "repair" job. It has worked well for 4 years now. I would like a slightly better grinder but will soldier on with what I have for now.
If I wasn't such a lazy guy I'd just use the French press. It makes a great cup every time. It's my go to unit for road trips etc.
I spend a LOT of time in the kitchen. I work from scratch with my ingredients and make my own sausages, bacon and pasta etc. At this point in my life I am sick of one use immersion blenders, stand mixers, coffer makers, toasters and food processors. I refuse to buy that consumer garbage anymore. Sadly all of the Brands crank out this landfill junk. My solution to this problem has been to buy commercial grade stuff from the US online webrestaurant suppliers. I have been very happy with the Waring Commercial line of appliances. Sadly as great as they are and they truly have that made in US look, they are made in China. Regardless the stuff is bullet proof and should you need to repair something the parts are available. Of course Sheilah was a bit touchy about bring home the 22 pound 4 slice toaster from a US business trip. One bagel and she quieted down.
As with our woodworking pursuits, we get what we pay for for the most part. I may be learning this finally. Apparently my stomach gets my attention.
