Looking for loph and M.luethyi seed or cuttings

[Glochid Fingers]

I am looking for Mammilaria luethyi seed and/or cuttings. I am also looking for any species of lophophora seed/ cuttings (preferably var. Caespitosa), and cuttings from a very fuzzy variety of astrophytum asterias and either of pelecyphora aselliformis. I hope its not to much to ask for right before the holidays If you think you can help me, pm me, or, if you can recomend any trustable suppliers in the U.S. please do.
Thanks.
