Yes it's very comprehensive. I'm pretty sure it has every single course.

I travel all over the country and if knew that the 10 most expensive courses were in NY, Miami, San Diego, Seattle, etc. I might strategically plan where to use my 3 rounds in the most beneficial places. No need to use one on the $45 course in L.A. if there is another course that's $200+ in some other area that I might be traveling to.

It may not exist, but I was just trying to avoid going to every single area in every state to see what the price was for each course.
