I first saw salt put in coffee in an old Charlton Heston movie! It might have been "The Mountain Men", not sure. Haven't been doing it lately, but I've put a lot of salt in the old Mr. Coffee basket over the years.
I decided to get a fancy coffee maker a while back and got a Cuisinart that grinds the coffee and brews it, on a timer if you want. Horrible design. The thermal carafe was low capacity, and you had to turn it upside down completely to pour. Then there were like ten parts that had to be disassembled and cleaned every time you used it. I put it away and then gave it away.
Then I found a little Mr. Coffee 4 cup maker at a thrift store for two bucks. Been using that ever since.
My relatives in Owego lost everything in hurricane Lee, right after Irene. They loved their big camp coffee percolator. I looked all over Ebay to find them another one. Finally found a vintage Revere Ware copper bottom percolator with the glass top insert. It came all the way from Riverside California where it was made. Somehow it came all the way to NJ and got sent back to the guy. I finally got it, only to discover it was not as big as I thought it was. I kept it, and it came in handy for a couple weeks after Sandy when we had no power. It makes good coffee but it takes a little time.
