After seeing some video reviews i think the combiner add ons are awesome. I started checking for prices and stuff on ebay. I am confused though. The prices are pretty high and it seems like these kits only contain one or two bots (if any?) and I would have to buy the others separately? Does this mean FP only makes one or two bots with the add ons included then I have to buy 3 or 4 Has/Tak toys too complete it? Or does FP only offer the add on only and I have to already have the all the bots from Has/Tak? And what bots go with each set? How do I know what TF's I have to have for each combiner? So, can someone fill me in on each of these sets, what they actually come with and what I have to buy separately to complete each combiner? Thanks in advance.
