I have played two wizards and both have had familiars. The first was a straight Wiz who took Improved Familiar so that I could have an Air Mephit. It was extremely useful and fun, except for that time with the Aboleth...
The other caster was an Arcane Heirophant, Companion Familiar was just sick. It actually had lower HP than half of mine (IIRC), but the feats it could take because of the HD made that worthwhile. Eagle with Fly-By-Attack and ranks in Tumble. Toss in Shivering Touch and life was made good.
