Funnily enough I've just built a TT01D, see my thread here: http://www.msuk-forum.co.uk/topic/116028-my-first-drifter-tt-01d-type-e/
There's a seller on ebay selling TT01D Type-E kits on ebay minus the electrics, shell and wheels, for a reasonable price, which was ideal for me as I wanted to chose my own shell, wheels and electrics. It's a nice kit to build, very easy and the quality seems great
