I made a solar filter for my C8 using the Baader astrosolar safety film. To get a sheet of the film was of similar cost to getting a solar filter made with the same material.
The view is white and very clear. I only ever use it to watch events that involve viewing the Sun like the transits of Venus and Mercury and the upcoming partial solar eclipse.
There is so much material left over that I have a ready supply to cover binoculars and finders. For the transits of Venus and Mercury I put a small piece of the film over the finder with a rubber band.
The film filters are a lot cheaper than a PST and are worth having anyway to observe/image these events with more of your equipment.
