Ninjor there will be your best seller, I believe. I know there is a collector store near me that has one without all the weapons for about $70. They sell better in good condition with the weapons, but i'm not too sure what kind of prices you'd be looking at to be honest. Have a peep on Ebay and get a feel for what others are charging.
Does your Grizzlor have the brown face (same color as arms and legs) or a really dark brown/black face?
