Depends on what you want to do.. If you just want to drive it around in a parking lot (we call that "bashing") then you've got a lot to choose from. I personally like the Tamiya TB-02, which is another tub-chassis, shaft 4wheel drive Tamiya kit, but it is a bit higher end. Because the TB-02 just got replaced in Tamiya's line up with the TB-03, the TB-02s are usually available for cheaper. Out of the box, they come with ball-bearings, oil-filled shocks, aluminum driveshaft, adjustable suspension parts (all the things that you'd have to pay to upgrade on the TT-01 chassis). I believe the TB-02 has a "d" model for drifting as well, just like the TT-01.

On the other hand, if you want to start out racing, the TT-01 has a good class for beginners going on (pretty sure it's big in the UK too, you might want to check?)
