Friend gave me my single cup Keurig for Christmas, last year. I have the refillable filter KCup. I use my own brand of coffee.

From what I'm told, my model is off the market and they hae a single cup now that you can determine the amt of coffee by the size of the cup/mug. I would rather have one of those NOW.

I just had a post about this, check the link.
I just got mine and I can not use the My-cup filters since my coffee maker is commercial. But I did buy the ez-cup hoping it will work.
I have only bought 1 box of K cups, its the Van Houtte French Vanilla. I don't care for it, its tastes bitter to me. Read the thread for more info.

I am more interested in the sizes of these machines. Do some have a larger water tank? So I get a second cup quicker?

We love ours, Joann. Ours is the multi cup, the cheapest not the programmable one. I just didn't see a reason for the bells and whistles on that one. There are so many different types of k-cups. Lots of folks love the donut shop coffee but we don't. I love Tree Huggers, my favorite is called Jet Fuel, both are from Coffee People. I get our coffee from coffee.org. I don't care for the EZcup, but it might be that our regular ground coffee just doesn't work well with it.

Mine just does the 8 oz cup with no reservoir. I figured, a six oz isn't worth the bother and 2 more oz isn't gonna make much difference anyway. If you use the k cup the 6 oz might be too strong or the 10 too weak. Its nice to have the option though in case you do want strong or weak. I got mine at such a good price or I would have got the one with different size cups.
Now I was wishing I would have gotten the new tassimo that makes 5-6 different types of coffee. I just saw the commercial the other day.

I posted on the other thread....love mine. I only have one or maybe two cups a day, so the single serve one works just fine. I still get too much water in it all too often, but it only takes a minute or two (while the eyes are becoming aware of the morning) and I can smell (OOOHHHH) it while it is filling the cup. Heaven....in only a minute or two. NANNY

BTW
I haven't tried the filter thingy yet....I think I would have to get it ready the night before because I am barely awake when I get my first cup.

I do get mine together the night before, so all I have to do is pour the water and push the button, in the morning.

I think the largest one with a reservoir holds about 60 ounces of water and you have choices of 5 different size cups; mine holds 48 ounces and I have a choice of 3 cup sizes. Even when I have to refill the tank it does heat up quickly again. Mine is the Sam's club version (B66) of the B60 - the difference is that it comes with a large assortment of K-cups.

All my friends and I adore the coffee from The Coffee People, Donut Shop, medium roast decaf. Everyone who has tasted it has commented on how good it tastes - not bitter and not too strong. We've also become tea drinkers witih the English Breakfast Tea (non-decaf).

My husband was very skeptical of using the machine regularly. However, he loves the Ghiradelli hot chocolate - comes in packets, not K-cups. Don't forget you can also use the Keurig to dispense hot water for hot chocolate, cereals or tea bags as well.

I have the single cup one and love it....no more throwing half pots of coffee away or drinking way too much everyday! I use both the k-cups and my own brand. Had it for over a year and it's been great
