I've heard more bad than good about Duratrax vehicles. Never heard of the other one at all. From what I've been able to find so far, the Ofnas seem to be the best thing going, pricewise anyway. They have a kit that's 80% assembled, no radio, no engine, on Tower's site for $239, I think. They look to be built pretty sturdily. How is parts availability for the Ofnas? I would think that buggy, coupled with the new Fantom .21 would be a screamer!
