Watch ebay, last year I picked up 8 bowls for around $20. Yep, they were estates and needed to be cleaned, but that's easily done. Gave a couple to friends, and still have a great rotation. I use Falcon pipe cleaners, because they fit a little better, and don't leave fuzz remnants in the stem.
If you're interested in color pipes, go to ebay.UK - that's where I bought my wife's green one. It's the very limited last batch of production, and they have no intent to reissue them. The black one was also an ebay purchase, and there seems to be plenty of brown and silver ones available. Perhaps it's just me, but a good estate seems to be made a little better than the new ones.
A Falcon, or even a Dr Grabow Viking is a good purchase. The Viking bowls are harder to find.
