"Counts as" Soul Grinders

I'm kicking around building a bit of daemon stuff, but don't really want to fiddle with acquiring soul grinders. Any thoughts as to what would make acceptable or even cool counts as soul grinders?

I saw someone use the Slaughterbrute as a Soulgrinder with a few added bits for his Daemons army. It was a Khorne themed army, so it looked pretty decent.

Forever and a day ago i found this guy as a possible greater daemon, but he is more about the size of a soulgrinder/ slaughter brute, I can take some scale pics if you like. A new paint job and a few guns added and he could do pretty well

also, don't take the website's price to heart, it goes for about 10-15 on ebay

Slaughterbrute was actually what I was talking about earlier, Eric. I think it would look sick.

Thanks for the advice. I'll check it out.
