Tony Kart is an extremely good chassis. Only gripe i have is the spares are expensive unlike Gillards and some others. But most the big companies including CRG which would be my other choice are pretty expensive for spares.
I'd a spare nose cone, side pods if you can, stub axles, bearings, sprocket, chain and that should start you off. Also a spare fully charged battery and some spark plugs.
Hope that helps a bit
