The main key to drip coffee is getting the right temperature of water to the grounds.
I have a pot I picked up for free. Actually it was a double, two pots on the same stand, you could turn each on or off as needed, each had it's seperate resivoir etc.
Long story short, the 'hot water pipe' from the heater ran right up through the water tank in the back and cooled down a lot. I put some insulation over it and it spit out 200 plus degree water on the grounds now!! The thing could not have cost more than 40 to 50 bucks at the store yet brewed an awesome cup of coffee now that the water temp was correct. From what I have seen, most 'general' coffee pots are easily 'fixable' to spit out the correct temp of water.
Why pay 200 for a technivorn, or 500 for this when a bit of tinkering and an 'ordinairy' pot can make a great cup of coffee, unless you just HAVE to brag how much money you spent on your machine to your friends?
Just my two coppers... (which if they are true copper pennies are actually worth about 3.7 cents now)
