I have enough money this week to buy some models, and I'm trying to work out what to get

I want to get the Gundabad Orc upgrade set as well as Guritz and Gothmog's Enforcer to round out my Morannon Orc army (there's another guy I want to get too, called Goroth, but he's no longer produced so eBay is the only option for that one). With those two sets, I have enough to get a third set, but I'm really not sure what I want. I thought about getting Raza and Delgamar because they'd be cool to paint, but I'm not entirely sold on them right now. I also considered getting the Army of the Dead Banner Bearer because I've wanted one for a fair while and it's the only thing I don't have for them, but again I'm not entirely sold on it at the moment. There's also Elfhelm, but he's the most expensive option and I'm not sure I can spend quite that much money (I think I can afford it but it would be much tighter than the other options). So let me know what you think through the poll attached to this post, and I'll get that one.
