Please talk me out of it. I don't even like the DCs drinking fizzy drinks - but DH and I get through a lot of mixers - but probably not enough for a sodastream to pay for itself in the next 200 years 
I think I'm just getting nostalgic about the orange and white one we had when I was young - it was the 'special job' to be the one who got to fizz up the water till it farted
. And you used to get some lovely flavours like Vampires Venom and Witches Brew. I was nearly salivating over a shiny new one in Sainsburys last night but I managed to drag myself away. Help me!
