It's completely market driven, and fabricator driven. 3 fabricators in the same market could have 3 different prices. The only way to know is to talk with the fabricator that you plan to use.

Also, there's nothing official about level 2 or level 3 - it's all dependent on the supplier and their pricing. A level 2 at one place could be a level 3 or 4 at another place.

Thank you.
