Tee,
No guarantee but I should have some for give outs next year. But my favorite is SMG Succulents, JadePoint Succulents, Mountain Crest, C & D Plants, & Simplysucculents. I have ordered from all of these with-in the last few years. I have found them way cheaper and better than Ebay. Miles to Go is also great but I purchased diffferent plants there. I don't know about their Echevieria.
