A decent very early spear is the one Ra'Vir sells with a bound-spear
enchantment on it. Devil spear or Deamon spear or something
like that. Getting the extra 10 in spear helps in the early game.
There is a dwemer spear in the Angmumble dwemer ruins just
outside of Fort Moonmoth if you want to enchant your own spear.
There is Ilkurok (or something like that) that is standing about
in a Dwemer ruin (the one the first Sadrith Mora fighter's guild
quest is in). It has +15 night eye, which is very helpful in the
early to mid game.
There is the Spear of Bitter Mercy.
I particularly like to enchant a lightweight spear (say silver spear)
with bound spear on strike. This gives you the +10 spear skill,
with a blade that renews itself frequently (does not dull out and
need repairing much).
Spears are a much under rated weapon. They are fast (though
not quite as fast as a dagger), have that nice reach so you
don't have to close completely with opponents and can really
knock someone back/down if you hit them with a good running
rush. There are also not terribly heavy. And, if you are not
paying to train up, they help you build endurance. A spear and
a medium cuirass pretty much guarantee at 2-3 point raise in
endurance with nearly every level up.
