3 or 4 years ago,Shamus (Don) did import a couple dozen buccaneers from Florida in all different sizes. I don't think he's brought any more in since.
I have grown this species from seed extensively in Mesa, Arizona over the last 25 years and have probably sold about 75 plants in 3-5 gallon size, although I don't currently have any available unless I dig one out of my yard. (I have about 20 planted) It IS a great species for our area,and I've found them to be very tough survivors;although very slow growers until the base is 6-8 inches wide. Importing your own from Florida is probably your best option. Be aware,they are not cheap, because they are slow growers no matter where they are started. Time is money...🤷♂️Growing entirely here in Mesa, Arizona,it takes me 10 years minimum to produce a nice 3-5 gallon tree. Definitely worth pursuing,at the largest size you can afford. Buying time does make sense for this species. To give you an idea of how slow they grow, I brought these 2 examples back from Florida about 17 years ago in 15 gallons pots.
