RLSButler,
There are still a couple of British balsa suppliers who cut their own wood; SLEC, which sources its balsa from Papua New Guinea and The Balsa Cabin which uses wood from Central America. There are suppliers, but I can't tell if they cut orr just supply wood cut by others.
My understanding is that SLEC use the Papua New Guinea company as they created their own plantations to give more control over the balsa quality than other companies which just harvest what they find growing naturally in Equador.
