re: I just entered the world of Keurig - Any must haves?

Keurig is okay if you use it for what it is. We use it for a quick cup when leaving in the afternoon or if I'm craving coffee after supper. My wife is a night nurse, so she uses it when she gets called out. It's a convenience thing ,that's it. I always make coffee in the mornings.

My wife enjoys the Green Mountain cups, they're pretty weak imo.
I have found that Gevalia, Krispy Cream and Starbucks cups are the strongest, if that's what your'e looking for.
