There are many, many doctors that do PLDD in many spine specialists offices. You don't need to go to LSI to have it done.
From a prior post on the hugely long Laser Spine surgery thread, there where a few posts about it and the costs that LSI charge for the procedure.
Without even including the travel to Florida from wherever you live, hotel costs and food, the cost was way, way more than having it done locally with a good spine surgeon, in a hospital that is close to home.
If you have any problems post op, by having it done close to home, you will have a doctor to treat and follow you. Whereas, traveling to LSI or any of the other laser spine facilities, once you leave them, you are on your own.
Good luck
