I think your perceptions of weak/strong/bitter/insipid might be off, as MikeHartnett points out. No matter what you do to that crappy coffee, be it French press, Technivorm or having the infusion made by hand maidens, it is never going to be good. I like Chris' suggestion that you brew some coffee with the pour over method, by using the filter and carafe from the Technivorm - having absolute control over the water temperature. No need to make a liter all at once - make a 1/2 pint - use the right amount of coffee, and go from there...fwiw, I think your grind is probably too coarse for pourover - I go the just the upside of an espresso grind for my pourover coffee. And buy some good roasted beans - Sweet Maria's is great - but you really have to understand the roasting process before you can be absolutely certain that the beans you produce are any better than, say, 8 o'clock's. You could buy some roasted beans from them, or Intellegentsia, or...
