There are a large selection of pre-painted fantasy figures available, made by Wizards of the Coast amongst others for the D&D and Pathfinder role playing games. Some of these figures are 'collectable' and as such have a premium, others are very reasonably prices.
I have touched some of these up and redone the bases. First up is a Snow Ape, just the sort of beast to be found wandering the ruins streets of Frostgrave.
This next model is enormous yet was only a few quid on eBay, I see this as an animated stone construct.
