Purchasing New Pieces, Desire Peer Opinion

Hey guys,

I play mostly to paint due to my current location being more 40k intensive as well as my lack of current rule book or Ogre Kingdom's codex, so if it isnt too much to ask I'm going to quickly post my list of what I have, and ask what you guys think my army most badly needs, so that when I do get around to playing again, I will not have purchased a new piece, which I have no idea the affects of, for nothing other than how pretty it is. I was mostly considering either those Mournfang Calvary, a Firebelly, Golgfang, or possibly some Gorgers since I have always wanted them? I only have about 40 dollars to spend, and this will be the last model I buy for quite some time due to income restrictions.

17 Bulls
2 Homespun Butchers
1 Homespun Bruiser
1 Tyrant
6 Leadbelchers
8 Iron Guts
1 Hunter
1 IronBlaster
4 Giants
2 Thundertusk/Stonehorn

So, with that in mind, what should I buy? (Other than the rulebook and codex!)

Oh, and before anyone asks, I have 4 giants because I traded my dwarf army for some money and some unopened giants, with the intent of green stuffing them to look like Norse Gods. I was going to attempt to make a Giant Codex, based on the fluff for giants given in a few of the other Warhammer Codexes, but I was awful at greenstuffing so that plan sort of fell apart.

Mournfangs, they will rarely let you down... Firebelly's are good too but I'd put bear cats first

Mournfang are very effective and scary cavalry units. Mine seem determined to ignore that reputation for some reason, but generally they're a powerful unit, though you'll need two boxes of them.

Maneaters - if you love painting and conversions this is the unit for you. Ridiculously versatile and very effective, these guys should be in every list - as they can do anything you want them to!

Yhetees - many people prefer Maneaters and consider these guys a bit rubbish in comparison, but it says something about how awesome our book is when Yhetees are considered rubbish. Very fast and provides a change from painting typical ogres too.

Gorgers - divides opinion, but they always look cool at least. Just one can be very effective, and honestly they've never let me down.
