Yup, try the Lancelot wood carving discs. they come in 4' diameter chain-style circular cutters in 14 and 22 tooth selections and arbor sizes 1/2 and 5/8. they list for $38.99
there is also an Arbortech disc for around $105. Haven't tried this one, but the Lancelot works great.
I think they have a website at
www.woodcraft.com, but I'm not sure. These are in several catalogs, but this is the only one I can find right now.
