I googled 'plastic vanda baskets' and a bunch of sites came up. I have heard of Tindara in a positive light: Tindara's Teak, Cedar, Plastic, Vanda, Orchid Baskets & Wire Hangers
but there are also others, many from reliable vendors. I'm sure a wooden one would work if you can find that locally, I just like the plastic as I know it won't decompose.
