If you need it now, I can't be of much help... but if you are have the time and inclination, the Seattle Fruit Society will have their spring meeting including various scion and rootstocks in March. I've got an old wild apple that isn't any good, and plan to get some scion cuttings to try to graft on. Hopefully I can get several other grafted trees at that meeting :)

Note that the rootstock I think has a nominal charge, so doesn't qualify as "trade", my apologies if anyone in the group feels that sharing this info here is inappropriate (I don't benefit from the meeting, just trying to share info)
