Slippery Slope

I have a significant Ogre force ready to go.  I have some
skirted hover tanks on order as well as infantry.

I just discovered the Rolling Hot page:

They seem to be claiming most of the Mini's were done by
GZG.

So now I want to do a Slammers set of mini's.  Are there
equivalent mini's in 1/300th?
