Speed Graphic's website said they had stock for two days after I ordered mine.
I guess I'm extremely lucky to have noticed them as I've been trying to get one for a year on various back order lists.
Absolutely love Lee Filters, they're very good IMHO.
Chocky - have you tried contacting the usual companies like Morco, Robert White to see how long the back order list is?
My advice is to get on a list ASAP as Lee only seem to produce them in small quantities and back orders are never fulfilled in one delivery...
