Which "Drip"olator will make
GOOD Coffee ?
“Drip”olator/electric filter machines
The simplicity of design, ease of use and convenience of a "drip” olator makes it
an excellent way of making a reasonable cup of coffee at home or in the office.
Why then are the coffees you get out of a "drip"olator often so terrible?
Because people do not know about the 9 Rules 
Even the most basic of "drip"olator machines can produce good coffee with freshly roasted and properly ground beans.
As long as you drink it straight away and not let it sit to stew on the hotplate it will be as good a coffee as a “hand-made" filter coffee.
Unfortunately it is the hotplate which makes the "drip”olator attractive to the larger home or small office: one batch of coffee for all, no matter when they turn up.
But, what these poor people are serving themselves is NOT coffee anymore; they are pouring a cup of dark-brown, overheated, bitter "drip"olator liquor… as in "medicinal potion", not of the alcoholic kind!
Ok, there is no argument about how to take your medicine…you prefer bitter and overheated, go right ahead! I prefer my coffee to taste like coffee 
If you want to use a "drip”olator, try to find a small one; they have a smaller heating element in the hot plate, so the coffee does not get so hot after it drips in the coffee-pot.
There are now Single-Serve machines on the nmarket, which are ideal if yoru household has only 1 or two coffee drinkers.
Other brands have brought out units which make 1 cup at a time, but can do that 6 times in a row, which would suit a small family or small office.
Generally a 2-3 cup machine performs the best, and a 4-5 cup machine is the biggest I would ever buy.
I would rather make two batches of good coffee for a large crowd than produce one batch of “slop” to fill all their cups at once.
Once you have your small drip-machine, run some water through it to eliminate any chemical residue from the manufacturing process and then start following the 9 Rules.
You will need the same amount of coffee for these machines as for the stove-top filters: 1 heaped tablespoon of coffee-beans for every cup.
Grind the coffee, put the grinds in the filter, add as much water as you need for the number of cups of coffee to the reservoir and switch the machine on.
When you hear the “gurgle” which indicates that the last of the water has been pumped from the reservoir to the coffee grinds, switch the machine OFF so the coffee already in the pot does not heat yup any further.
Pour the coffee as soon as the filter has stopped "dripping".
