Probably. RN has some nice looking sets and a great vendor. But since you asked for an alternative, you can also consider that they are out there. Some are stronger oem replicas like RN's, others are custom metal door skins like those from American Dirt Roads. I assume you're after the prior.
I bought a really nice, thick aftermarket set from a guy in BC about 8 years ago. Found him on google or this forum. I have since given them away, otherwise I'd have more info for ya. I believe he had a plastics company and did a run of them. I hope he is still in business because I could use that set now as well! Anyone remember him?
Edit: Found him
3 min. on google ;-)
