Steve,
A number of posters here operate quality nursery businesses. I'm not saying that you should or shouldn't order from Oasis; I'm just wanting to list a few member-operated sites for your consideration that you may not have discovered yet:
Northern Tropics
Rare Bananas
Encanto Farms/WeBeBananas
Brian's Botanicals
Plants That Produce
I'm a noob and have only ordered from one of them so far (Northern Tropics, positive experience), but they've all received high praise from other posters.
(Apologies to any member-owned businesses I forgot or haven't discovered yet.)
