To be honest I personally don't know much about the Ofna LX. I don't know anybody in my area thathas one, and none of the LHS's around here even sell them.
I think I remember reading some where that people were having problems with some of the parts being weak, and breaking easy. I could be wrong though.
I am in Salt lake City, and have a good amount of hobby shops around here. The fact that not even one sells that particular buggy would make me advise against it, just my opinion.
