Excellent advice. I would add that the Starbucks Via instant coffee stands alone at the head of the class, in terms of quality for instant. Tiny granules dissolve without need for filter, and weight nothing. The backpacker's friend.
Are they any good? I've thought of buying some. I've got a little Melitta pour-over that I use at work but it's just so damn messy. I've thought about breaking down and buying another Bunn for work, the one I have at home is awesome.
