I have 4 Keurig machines. 2 older models that I use at my office and 2 new models at home. The 2 new models are the 2.0 models and do not brew most cups. This was initially a problem for me but I figured a way around it. First I was just cutting off the top of an approved on and putting it on my favorite brand (which is not Keurig approved), that worked until I happened across the company that was giving away their clips. I received it, popped it in and never looked back. The clip works wonderfully and I have been able to brew anything I wanted through the system just like I was able to do with the old brewer.

I did read at one point that the way to obtain the Keurig brewing seal on your k-cups was that you had to have the beans roasted at their facility or something like that. I searched for the article before writing this post, but can't find it. I'm sure one of you folks could discover it.

As for the price of the coffee, I'm paying anywhere between $.05 - $0.11 a k-cup and when I brew, the brand I prefer is actually strong enough to brew 3 cups of coffee out of the same k-cup (2 if you use the largest cup setting). The price of the k-cup can be affordable with some savvy shopping (I use Amazon subscribe and save coupled with coupons). As the only one in my house who drinks coffee, I can't drink an entire pot at a time and that results in a waste of coffee, so the minimal expense of the k-cups is worth it.
