I got the $15.00 Senseo a few weeks ago. The only adaptations I make to it are I fill the reservior with hot water and I microwave a mug 1/4 full of milk before I add the coffee and it makes a nice little "latte". I recently got the vanilla-caramel also.
HOWEVER, aside from the van-carm and the dark roast, thats about all my local stores carry. They do have a wider selection of pods like Tassimo. Has anyone swapped brands of pods?
