ASO? (Anvil Shaped Object?)
You may want to see if the anvil actually has a hard face, or is cast steel. Supposedly some of the import anvils actually have a good face, but many (most?) are just solid cast iron, which is soft and will have poor recoil or bounce. The iron anvils will damage more easily. That said, for a few weekends of playing around, it may not matter.
My only concern with all of these forges that are made from ceramic wool. You really should cover the wool with something. Some sort of ridigidizer or refractory. The problem is that the ceramic wool fibers are not good to breathe. If the wool is coated properly, it keeps any from blowing out to where you're working.
