I've had a kyosho sport. It lasted one day of bashing. Complete rubbish. I also have a hyper 7 which has stood up to well over a year of racing and bashing. Its very good (read durable) and fairly raceable. It may not be the prettiest buggy but it is the miniumum I would recommend to anybody setting out in this hobby. Anything less will end up filling a cupboard or being on ebay to pay for your next purchase because it wasn't upto scratch. The hyper 8 is better.
Of the OFNA range the only ones to consider are
Any hyper 7 variety
Hyper 8
