Sorry Bengal, I've been on rather extended leave!
Yes, always make my own. I often make the pre mix stuff (hansells?) or I buy a natural yoghurt (not nestle!) and make my own from scratch. I'll be honest, I add sugar etc. I'm don't mind natural but the DH and kids prefer a sweeter yoghurt.
I make my own because I know what is in it - ie how much sugar, no gelatin etc. And because its much cheaper. And it's one less thing I have to buy and lug home. When we run out, it's ok, I can have another batch ready my the morning.
I have an electric yoghurt maker, but because we caravan a lot I make it in a thermo pot. Heat the mixture to 38ish, place the pot in a second pot with 50 degree water up to half way, then leave over night. My mum used to put it on top of the hot water cylinder (it was inside in a cupboard). So it doesn't even use any electricity. You just have to remember to take out enough to make a new starter culture for the next batch.
