I briefly tried it after Vapefest 2010 as i left with a load of giveaways from DV. Only had moderate success. Doodlebugs dad Pete (nicoteen) described making juice as being like making a cup of tea, no magic to it.
I think the whole home mixing thing has moved on with stacks of advice and techniques. No one spoke about steeping back then for example.
So I've stuck to ready made stuff and as you say Gareth, we are spoilt for choice of some great liquids.
i did have a bash again a few weeks ago and made a simple tobacco juice. It was ok actually but not sure I want to be bothered.
Things may change if taxation hits
