Quick rundown, in my opinion:
PRM - best quality, high price
High Lifter - for the same money, get the PRM
Aluminum Products - don't have much experience
Ricochet - good quality (it's no PRM), 1/3 - 1/2 the price of the others
myself, i went with the Ricochet. Caught it on special - full belly / nose skid, and all 4 CV guards for $215 shipped. Couldn't pass that up.
