Dario is bored perhaps?
On the realistic end I would like to get one ready for training - any source suggestions
When you mean source are you referring to information or actually purchasing one? I don't know if you would be interested in this. However, as of a couple weeks ago, New England Bonsai had a pretty powerful specimen for sale. It looks like the only thing that was done, was to give some very basic structure to the branches. If I remember correctly, it has about a 5 inch base and is only maybe 11 inches tall. A very old looking tree.
I don't think it is on their site. However, if you email or call, you can probably get a picture and some info on it.
