Yeah they're high, but are Porterbuilts worth it?

['65Burb]

I am intently following the hard and industrious work posted on here about the pancaked front cross members. As one who likes the feeling of accomplishment in a job well done, doing that work on my '65 intrigues me. However, after the many references to the Porterbuilts, I decided to look them up. They look like really neat units. Who on this forum has them and how do they like them? Thanks.
