Coronado BF5 or Lunt B600 blocking filters are in my opinion claustrophobic. I don't recommend them. I recommend at least a Coronado BF10 or a Lunt B1200. I also recommend pressure tuning rather than tilt tuning. But now you're getting into the big bucks.

Most importantly with solar scopes, I think more than with regular scopes, is that you need to have the ability to compare your scope to other similar scopes to ensure you have a good one and not a bad one. This is very much true with the low end PST scopes, but alas is also still true on the high end.

By the way, I think a Herschel wedge is only marginally better than Baader Astrosolar Safety film. Head to head with everything else being equal the wedge will beat the film every time. But a slightly increased aperture on the film compared to the wedge and the film wins hands down. And of course the film can be used with almost any type of telescope including SCTs and MAKs. For example, a little 8" SCT with a full aperture film filter is way more convenient than an 6" refractor with a wedge. (Before everyone attacks me for heresy, I have and use both.)
