Look on DMS, they have a crakin deal on the mini t or b with Exotek coversions included. mini t pro with tub chassie exotek kit for 60 quid. Amazing fun. 3 guys in the club just bought one. fantasic deal. Also there is a B version which has a full carbon convertion or some thing for around 100 quid but make sure its the uk edition if you going to race it in uk lol
DMS dudes are on oople, have a search for them, very helpfull.
But the mini t pro out the box works really well considering the price. great fun.
