If you really want to start a collection I suggest you start to buy Bandai figures for a couple of reasons 1 they look just like the monster in the movie very detailed 2 Bandai figures are cheap to buy and in time they will go up in value. Older bandai figures are expensive thats because they have gone up in value. If you cant afford the regular standerd 8inch figures then start off with the smaller 6inch bandai figures. You can get the figures from Clawmark toys they have the largest selection
