I can't say as I think the MT\R's are worth the money. I say that as a mudder, not a rock crawler.

I'm a bit cheap so I got Wild Country mud's, they work great and were about $100 per. Friends that I wheel with have that Walmart mud (can't think of what it's called) and it's got a nice tread pattern, comes with a great warranty and is inexpensive.
