I do have one. It is a single extention model: 8012L
It caries my 8x10" and 7x17" who weigh up to 10KG including lens and Gitzo R4 head.
The finish of the wood is very basic. The legs tend to bend a bit when spread wide out.
Metalwork is OK but the clamps' screws need adjusting every now and then.
I can't compair to other wooden tripods since I haven't seen any other in my life!
Contact with the factory was OK. I think they do have a dealer in the USA, you might ask them first.
Greetings,
