Hi Chriswg
I have a spicesofindia Tandoor and Im having loads of fun with it.
One of the best things I have bought.
Its good because its portable so I can keep it inside when the weathers cold.
Im sure frost and porous clay are a bad combination.
Its a bit heavy (35 - 40 Kg) but its got some good heavy duty casters and a good zip up canvas cover.
