I have one.

(Just the lower section with an SMA upper section)
Pros: I personally think its a great bumper. It provides more front end protection than anything else on the market. It retains the stock approach angle and acomodates a 12K Hydraulic winch. It takes rockcrawling abuse very well and has rock solid recovery points!
Cons: I do think the cost is silly. I bought mine used from another forum member for a very reasonable price. I don't like RA's upper section guards or corner guards. They just look over done IMO. Sfox and Phil always tell me my truck looks happy.
Overall, I have been very pleased with bumper but I would have a hard time paying full retail price for it.
