imho it all depends on the resources and equips available to you and your goal (fast zeny or fast levels)...
the cheapest most accessible spear nowadays seems to be the hellfire at around 400k each... sure it's two-handed, but use it with pierce or brandish and you know all those earth enemies will fall...
so, although i hate to say it, go to moscovia and pierce them... or round up sandmen and brandish them... sandmen are easier to mob and is relatively easy to kill... gives some good drops too
or if you happen to come across a gelerdria, then you could totally pawn hillwinds and never fear in using fish because killing hillwinds come with a money-back guarantee
or invest a bit in a VVS wind lance or something and go to marcs+swordfishes...
GL and HF!
