keurig sucks. Nothing that puts the water through in 20seconds will ever taste right. Also very pricey (per cup and for the machine)
I'd go with a SCAA certified coffee pot.. but I'm serious about my coffee.
The cert. shows it was tested to produce the right temp water etc.

Bunn Phase Brew 8 Cup Coffee Brewer
I personally have the technivorm moccamaster, and a bonvita 1900ts
The Technivorm is slightly better but both are excellent.
I dont own but have personally used the Bunn phase brew, OXO 9-cup, and a behmor model.
All were also exceptional.
Behmor is the brand of my coffee roaster.. they just branched out into more coffee gear.
Get the melita unbleached pore filters if you prefer paper.. or a good stainless one if you prefer more sediment and full oils.
For single cup if you dont mind fiddling with it.. an aeropress will produce amazing coffee.
