i second that, i own a EB4 S2 and its got to be the best little buggy i own, ive abused it and bashed it over the four years and ive never really had any serious problems with it at all, sertainly better than my kyosho inferno neo. the only two weaknesses ive found with them are the upper wisbone rear links are made of plastic and bend, i bought the aluminium set for a tenner that solved that straight away and the steering knuckles are made of cast ally and the bottom threads tend to go on the bottom ball joints, ive threadlocked them in tight on my second set of knuckles and no problems since.
also thundertiger parts are dirt cheap too so if you do manage to break anything its cheap to fix which is a bonus
