I haven’t looked at the machines for a while but it looks as though the smaller machines that take the original Nespresso pods have been phased out. I bought my son one for about £89 when he went to university but it is no longer available.
There is a small cheaper one in the range but it takes the newer style vertuo pods, and I don’t think LIDL do them. (They are probably still only allowed to be made by Nespresso I would guess)
There is one machine, De’Longhi Inissia, on Amazon for £114 that takes the original Pods, but I have only ever bought the Krups ones and my machines directly from Nespresso so can’t actually recommend it.
