I recently bought the smallest Lavazzao Jolie model from amazon.They were doing a deal where it cost just over £50 and included 36 capsules. It's very simple to use and just makes good black coffee with a sort of crema topping. You can get capsules in a wide variety of intensity. They do a range of ecofriendly ones too. Warning - you need small coffee mugs/cups as the compartment you put them is not very big. I wouldn't recommend if you are likely to be making more than 1 0r 2 cups at a time.
I've got the Tassimo. Works well and dies what I need. I do lattes for visitors, which are very popular. You can recycle the pods, I sometimes buy a big order direct and they send bags.
I am looking to buy a machine for coffee pods which does not need a technology degree to operate. Any thoughts on Tassimo v Nespresso? Or anything else?
