I don't know if you had heard of these guys but they might be worth a look.

The guy that runs it is a good bloke and a member here. I haven't bought off them but they seem to have good reputation but with seeds you never know until you put them down.
I might be able to send you some Loph willy seeds ( my own ) I will have a look over the weekend and see what I have.
I can post picks of the mother plant if you want.
Cheers
