For people getting into the hobby and looking for muskets there is Armslist.com and gunbroker.com . It is not uncommon to see Enfields at gunbroker selling for around $650, we're talking about the nice Italian stuff and not the Indian made junk.
There are lots of the (unclean [farby]) Zouaves for sale at both sites. Also, Armslist has the "weird" stuff like musket caps.
This is just information for people to use at their units. I would not sell an Enfield (don't care for the Springfield, just a personal thing) because a better Italian weapon shoots just fine and the Enfields are not a half bad deer rifle. In my state it gets another two weeks to the deer hunting season.
