7th Ed. Expanding from the battalion?

[SiegeCommander]

So a while ago I bought the LM battalion, and now that I've got a few small games under my belt I've been looking to expand my army more towards the 2k points region. I wanted to build more of a take all comers list. So far in addition to the battalion I've bought a slann, a scar-vet on foot, a stegadon, and another block of saurus. I know I'll definately need more than 12 skinks so I plan to buy a box of 24. With all this stuff I'll still be short a couple hundred points, so I figure I got enough room for either kroxigors, terradons, razordons/salamanders. As far as usefulness goes which of these units (krox,terradons, razor/sallies) ranks higher and why?

As champion of some random temple guard unit, I command you to get some more (should atleast have 14 IMO)

Also, salamanders and terradons are good bets, the terradons can take out enemy war machines and lone mages etc. and harrass the enemy army. And Salamanders can send entire armies panicking if your lucky (like goblins)

Lol. I would go sallies, and here's a tip, buy a box of flesh hounds of khorne, a bag of random square bases, and put a little bit of something over the marks. PRESTO! Cheap sallies... just have some x-tra skinks to use as handlers...
