I usually try to find a good condition Walsh cane on one of the auction sites. They come up for auction more often then you might think.
Viking also has a good metal appearing cane however they are temporarily out of stock at this time.
Our magic club, Ring 333 (The Fox Ring), is having a magic flea market and auction this Sunday. If you are interested I could check to see if anyone has a Walsh cane. Just e-mail me at firstname.lastname@example.org
