Depends on your budget and they're not easy to find these days.
I bought a good limited edition wooden ball vase from Merlins of Wakefield who are importers of items from The Collectors Workshop.

It still cost me £180 a few years back for the large vase, although they do a smaller version for around £120 to £140 but they go in and out of stock rather quickly. The quality is very good and you get a nice routine to start you off.
I'd love to be able to buy a Five of Hearts ball vase though
