CAD if nothing else. They make good backfield scoring units and occasional tarpits and road blocks.
Also Necrosius from
Apoc 2013 by forgeworld also allows plague zombies to be taken. He is much cheaper and buffs the zombies with furious charge so arguably a better choice for most "Zombie Apocolypse" style armies or low point level zombie armies.
Additionally, the Renegades and Heretics army list from Imperial Armour 13 can take a large zombie unit which is very cool. These are probably my favorite
40K zombies as when they destroy an enemy units (or cause it to flee) they generate 1d3 additional zombies.They also get
FnP 4+ which feels more shoot them and they get back up.
Some important things to understand about zombie units is that they are so slow that most armies can kill enough models from each unit to undo nearly all of your movement. Additionally after about 150 models your deployment zone starts getting packed and you may have to space them closer together. This means thunder fire cannons and wyverns will chew through ~200 model zombie armies like you cannot believe.
Beyond the first 30-60 zombies you have to ask yourself what you expect/want from this army. I use a zombie
Apoc type list to good effect occasionally but the key thing is that all of your killing and forward scoring has to be accomplished by other units. The zombies will only ever provide good board control and scoring in your half of the board. You can never count on them making it into your opponent's deployment zone unless and until you have already done so with your faster, more durable, and more damaging assets. This is why my "Z-Day" lists always start with the most damage dealing units I can get and then add 5-6 units of 20-30 zombies. Units that you should consider to make a Z-Day work from best to worst (
IMO);
*Fire Raptor(s); incredible flyer. With the autocannons this thing is a real gunship
*Sicaran; this is your answer to fast skimmers which make a mockery of your zombie units. Try to charge your zombie wave forward against a serpent or venom spam list and you will learn futility, try it with one or two of these and you will never leave home without them.
*Rapier Batteries; tough and very effective long range support
*Hellblade(s); for
AA duties. Not needed if you take fire raptors
*Dreadclaw w/
CSM + Kharne
*Last Memory Terminator Sorcerer w/ Nurgle Oblits
*Dreadclaw w/ Chosen w/ meltaguns
*Heldrake w/ baleflamer
*Be'Lakor; shrouding and invisibility can really help the zombie survive but against Tau and Serpent spam the game spins out or control too fast to make use of him and his points would be better spent on some of the above units.
Hopefully that helps as I love my Zed. (yes I did use about half a dozen different zombie media references in this)
YES. Listen to this man, his word is the word of
GOD.
Just kidding ansacs, don't be offended

Your advice is absolutely perfect, and will actually let him win a few games, which is always nice.
However, as I'm assuming he meant to play a fluffy list, I doubt he could really accept most of those...
Anyway, In a zombie horde list, I'd play from 60 to 120 zombies (depending on points levels), and associate them with the sort of über-killy units that ansacs mentioned. Furthermore, you've gotta remember that zombies are fluff-wise just useless fodder, that are brought into combat by their master to backup another force. However, you've gotta decide if you're more obsessed with Typhus or zombies in general?
If you prefer the zombies, forget the
CSM codex entirely, and use the Renegades and Heretics list with it's
FnP 4+ zombies, and back them up with the list's excellent heavy support choices (MOAR PIEPLATES!), and a few outflanking units and stuff to grap some objectives at the end of the game (or find some way to infiltrate zombie hordes, that's always fun (Ahriman ally much? He'll let you take those Sicarans, fire raptors or Rapier batteries that make
CSM so awesome)).
If you prefer Typhus, keep your Codex but focus on the one or two "mini-deathstars" (big and killy units) seconded by Zombies that slowly march up the field.
Try hiding shooty
HQs like Ahriman in huge blobs of zombies, or putting small squads of zombies and Kharn in a Land Raider (although this breaks the fluff in lists outside of "black crusade" lists with black legion painted units).
