Hi! I have the B50 - just recently. I gave my old B40 (only a year old) to my dd's dad. I got the B50 at Costco. Actually bought 2 of them, one for a gift. It includes Bonus Pack: 72 Additional K-Cups (90 total) & My K-cup attachment. I believe I bought it for less that what is on Costco's website - I think it was $139 +/-. Here's from Costco's website (with my own notes tossed in): 18 K-Cup Variety Pack (this 18 k-cup variety pack came with my original B40 which I bought at Targets - if you do purchase there, open the box and check expiration dates)Additional K-Cup bonus pack includes: 18-pack: Gloria Jeans Hazelnut 18-pack: Green Mountain Sumatran Reserve 18-pack: Tully's French roast 18-pack: Timothy's Decaf Colombian My K-cup Reuseable Coffee Filter: allows you to use your own ground coffee (this alone retails for $14.95 - I bought a single bag of Mackinac Island Fudge coffee from Krogers a couple of days ago to try My K-cup and it was awesome!)Go to costco.com and type in keurig in the search area (I'm a newbie & cannot posts urls yet) For the differences in the B60 and B40, check out keurig.com and also Single Serve Coffee website's forums singleservecoffee.com they have a nice forum with lots of opinions. We aren't allowed to use the electrical outlets at work so I caved in and had a coffee from the coffeemachine at work the other day - ended up throwing it out. I'm spoiled now by my Keurig. I have found some packs of k-cup coffee on clearance at Target (which haven't expired) and bought those also.
