I have a Technivorm. It brews a fantastic cup of coffee. I am also a consultant to the coffee industry so I work with many different brewers. The Bonavita is also a very high quality brewer. French Press and pour overs are great brewing methods, but even for me, are a bit overkill when I want something quick. So I use my Technivorm every weekday morning, and a French Press maybe one day on the weekends.
The one thing on K-Cups - they are convenient for a single cup. Not the best, but if I want a quick cup of decaf after dinner, I can live with it... Brew on the 8 oz setting (never 10 oz). Peets has a very good line of K-cup coffee. Percolators produce very bitter coffee. This is due to the over extraction of the coffee. Your better K-cups (the ones which are a plastic capsule and not exposed filter), are flushed with nitrogen to keep the coffee from staling.
I try to keep out of these coffee discussions - just too much mis-information and opinion for me to respond to...
Since you know what you're talking about can you confirm/deny an article I recently read that coffee beans can sit around in warehouses for years?
