Did anybody who has this scope find a solar filter they really like for it?

Most people will tell you that the Baader Film filters would be the best choice.

 

I would say that it is a the second best choice behind a Lunt 1.25" Wedge.

 

The wedge costs a lot more (about $230 vs about $50) but the wedge is a lifetime purchase (Foil can develop excessive pinholes after a few years) because the 1.25 wedge will work with any refractor up to maybe 110mm, and the wedge provides better performance.

 

The Baader Filter is a great filter, but the wedge is better.

Amazon is selling a Gosky branded filter with Baader film for a very inexpensive price.  It fits nice and will come off easily for totality. (I'm imaging it with my SV80ED)

I didn't know there was such a thing.

Another vote for the Lunt wedge here. It's slightly better than Baader film with my ST80, but the difference (visually) is negligible. However, on the SW 100ED, the wedge has a noticeable edge and, as Eddgie says, it won't degrade the same way film will.
