The Bosch Tassimo machine is a bit of an indulgence. However, the coffee is very good. Its extremely easy to set up and use with minimal controls - one button operation really. It comes complete with a drip tray, which you might need to remove for a standard mug as it can lead to overflowing. The discs can be quite expensive with the average price per cup somewhere around the 40-50 pence price. Some choices are cheaper and there is a good choice including Kenco, Costa, Suchard and more. You also get £20 off your order online through their website, however this is a one-off and you can easily buy the discs in the supermarkets.
I am not a huge drinker of coffee (one a day at home with the occasional one in a coffee shop). So for me this works, its not too expensive as I don't drink too much and works as a very easy to use coffee maker. I have tried the Costa discs and can say that they are not as good as in the coffee shop but are better than most homemade coffee. I am using it on a daily basis and as such its a good coffee maker that's worth the initial outlay and the follow on cost for the discs.
