my old standard; easy to use, perfect for those drowsy mornings, consistently great coffee, i keep coming back to it after playing with my other vac pots.
Positive Product Points
C50 is by far the best model of any of the coffeemasters, don't touch a C20, maybe a C30B or newer....
an example of american engineering and manufacturing excellence from the 1930s, 40s and 50s.
automatic, doesn't need to watched.
with the C50 you don't have to fight to remove the top tank.
gorgeous chrome plating on brass/copper.
Negative Product Points
the dwell time for the coffee in the top tank may be a bit long resulting in a pretty strong brew for some people. for me, its just right.
some people have complained about possible burning of the coffee when the coffee makes its first drop attempts.
nothing else that i can think of.
Detailed Commentary
this is the one i keep coming back to after playing with all the others. totally automatic.
easy to fill with water, attach the top tank, add the coffee, turn the knob to brew, plug it in, then walk away.
with the two bakelite flippers which expand the neoprene o-ring seal against the opening of the lower tank, it couldn't be easier...
cleaning requires just a quick swish of water in both tanks, and an every-so-often clean out with baking soda to get the film of coffee mud out of the top tank.
instead of using the standard stainless metal mesh filter, i use the nicro metal dome and spring filter. avoids stalling and much easier to clean up.
Buying Experience
they show up on eBay all the time, the last two i purchased at a local salvation army store for under $10 each. should be able to get a good, complete one on eBay for under $25.
