We've decided against halogen now after being on a 6amp site when all the halogen did was trip the electrics, instead bought a gas kettle bbq with lid and built in thermostat so we can use that as an oven instead and not have to worry about the power usage
have to second the andrew james 12L halogen oven, if you look around at the moment you can get them for 42.99 with 40 quids worth of free stuff and they are great cookers, and as said before the lid rest is a godsend for not melting your tables
I've just ordered one! I think we will have to take the duel fuel cooker this time as I won't have much time to practise with the halogen but looking st it as an investment for both my kitchens!
