Tiffen Graduated ND 0.3, 0.6 & 0.9 Filter for Cokin P (approx 3 1/3"x5 5/8" - Extra Long) $99 each
I primarily used this for film but handy for digital also but I don't use anymore so clearing the camera closet.
B&H price $169 each.

I also have 2 cases(extra) for these filters and will include if you buy all three; or one case included if you buy 2.
If you buy all 3 I'll pay for shipping in CONUS
This is for the Cokin P series filter holder
