I have that particular seller saved as well. His material is always interesting with twisted trunks, but I highly doubt the branches wire well (brittle) and the foliage may also be unreliable with occasional dieback. I'm basing this on experience with Rosemary, which make some great trees but have the problems mentioned. Keep in mind that shipping plant material into California is ILLEGAL unless the material is inspected and has actual papers.
You may want to try collecting old rosemary bushes. Ask some relatives, friends, or neighbors if you could dig a tree and replace it with a younger, "nicer" one. There are about 2 dozen spectacular ones down the street from my girlfriend's house I've been eyeing for a while. They get twisted trunks and deadwood easily, and make great literati.
