Yaesu FT-817ND: Mechanical CW filter suggestions?

I mentioned in a previous post that I recently purchased a Yaesu FT-817ND package from a friend. The Yaesu had a number of upgrades including an Inrad SSB filter. Thing is, I rarely need a filter when operating phone, but desperately need one for CW since the the default filter width is quite wide.

Although I plan to purchase a SOTAbeams Laserbeam-817, I’d still like a narrow mechanical filter for the one available filter spot on the FT-817ND.

It seems the YF-122CN (300 Hz Collins Mechanical Filter) is no longer manufactured. Used prices can be quite high.

I’m curious if anyone has suggestions for alternative narrow CW filters? Please comment if you have any advice!
