I havent gotten a price from Relle yet but Gunsons quote was pretty heafty. Almost 20k more than alfaro(although he did not give me any measurements) for his fee alone. Gunson also threw in cheek augmentation.
If Relle's prices are similar to Gunson's then my above statement regarding prices is true.
Alfaro is likely to give a plan more similar to Gunson. I think he may be a good option for you since your bite is not a significant issue. The reason he won't give you a tracing right now is because he typically takes the 'surgery first' approach. Other surgeons pretty much have to give you a plan because they can't just say "ok spend $7k on braces and i'll tell you my plan in 6 months". He did give me one, but I think that's because he considered pre-op braces a possibility in my case.
All 3 surgeons are competent. The way I see it is this:
Gunson: More attention to detail, large rotations. Probably best for cases with complex bite issues. Exorbitantly expensive.
Alfaro: Also large rotations. Tends to propose a slightly better chin for men than Gunson. More reasonable prices (both surgical fees and hospital). Best for cases requiring large rotation where the bite is already pretty good.
Relle: More conservative rotations. Prices are reasonable (I think, need to verify). Best for people who are risk averse and/or needs less rotation.
My reading of this is that Alfaro could be the best option for you depending on his plan and your risk tolerance. I think it's hard to justify Gunson's prices in your case since your bite isn't a major problem. My concern with Relle's plan is how far forward he is bringing your ANS. That's the opposite of what you need. However if you got a rhino first, all that is potentially subject to change.
