I found an online source for the HA Mack beechwood spoons!
Fante's Kitchen Wares Shop in Philidelphia - their website is http://fantes.com/utensils.htm#beech
You can get the complete set (10", 12", 14", 16", 18") for $14.45 with $6.50 S&H.
SurLaTable has a set made from boxwood - they are $56.75 for a set of the same sizes.
If you want to try to find a local source - you can email HA Mack at firstname.lastname@example.org
and tell them you're looking for a local source for their French beechwood spoons, and be sure to tell them where you live.
