I've switched over entirely to exposure bracketing and HDR software, so I no longer use my 4x6 Singh-Ray grad filters. I have both a hard and soft step 2 stop graduated neutral density filter. Both come with original padded case and are E to E- condition using Adorama's criteria (http://www.adorama.com/catalog.tpl?op=itemlist&cat1=Used&cat2=Filters
). New $160 each.
I'll pay shipping. $95 each, or $180 for both. If you buy both I'll throw in the Cokin holder, and a 58, 67, and 77mm ring adapter so you are all set to use the filters with lenses of that size.
