What Hydrogen-alpha filter to get?

Looking for a HA filter for the sun, and interested in thoughts and suggestions about the different ones out there. Between Coranado, Thousand oaks, Lumicon and Daystar what are the differences. Looking for both visual and CCD, as well as using the filter on different scopes, from a 80mm f/6 refractor to a C14. I'm not independently wealthy, so would like to keep the price reasonable... the $15,000 filters are not an option.

I saw the article in Astronomy, but it left out the Coranado filters.... the PST is not something I'm interested in. I want something I can move between scopes.

Thanks
