As some may know, I take classes with Werner Busch. His www.bonsaiwerkstatt.de/Bonsai Werkstatt
is the base of many bonsai addicts and features a museum, pots and tools section and a large range of trees, ranging from young seedlings to fully styled Yamadori. If in the area it is well worth a visit and all budgets can find something here.
