They are easy to change, do it yourself with some jacks and jackstands, no special tools needed, or any shop should do it fairly cheap.
I can't see not getting the ranchos, as they are adjustable and can be tuned to your preference, but if you don't likethe OME shocks, you are SOL. I do a lot of wheeling, so I am adjusting them from stiff to soft fairly often.
