I don't even think that for a twink war/pal this would be a good weapon ... remember the damage caps. Under level 10 the damage cap is set at 10 weapon damage. Under level 20, but over level 9, it is set at 14 weapon damage. (IE - under level 10, any weapon with 11 or higher damage hits like a 10 damage weapon, and from 10 to 20 any weapon 15 damage or higher hits like a 14 damage weapon). With the 31 delay, this weapon's damage is worse than using a SSoY at level 1-9.
2 were selling for 3k, 1 was selling for 5k. I personally think the price is a bit extreme at this moment, even IF it does have 18/31 +10AC. Stats are OK, but not great.
There is no level restrictions on this weapon. For a twink warrior / paladin this is a decent weapon. That's why I would assume the prices are varied and up in the 1-3k range.
A lvl 10 War with twinked gear +10sta & 20 hps.. Decent dmg and delay for low level zones. This makes an awesome twink weapon.
As for the weapon itself and the risk vs. reward. This weapon is stinkin pretty bad.
