I think Steve and Ross are about it for commercial seed quantities. Ross's is good quality, so I've heard, but haven't had any myself. Most of us who get into the hills collect a bit for private use. You could contact Dave Toole (Forum member) who would probably be interested in swapping. But Dave will be having major psychological and anger management problems at present with the news a couple of days ago that a London-based company is to start drilling for oil behind the Remarkables Range, in the Nevis valley (Ian Y knows the area), one of Dave's happy hunting grounds. Why don't they keep their bl....y oil activities off shore, as previously?
