Unless you really have fun gearing up at low levels, I wouldn't bother going out of your way. The low level gear is only really going to make a big difference on a class that depends on gear like a warrior. Any caster is not going to get much out of gearing up at anything under 60. You won't get any damage buff or anything. Mostly all you'll get is more mana, which could help you cast another couple of spells before you're out of mana. I don't know that spending 10 runs of SFK is worth that. In the outlands, you start getting a ton of damage buffs and significant mana regen buffs, which will eventually increase your power and endurance tenfold, so it becomes worth it then.
