What do you want? Check out Adorama - I can pick up this Saturday.

Thanks Dave. Unfortunately, they don't seem to carry those sort of filters.

OK - by the way, I met Mike People's in Adorama, NYC, on Monday. He's the bloke who took the Supernova image. Now, *that's* a small world :shock: Gave me free Televue baseball cap

Anyhow, delivery is due in about 24 hours...
