I've been hoping that someone would make a comprehensive line of "Megazords" (not sure what they call them in the Sentai series). Can anyone please answer some questions about these?

1. Are these the same size of the Retrofire Megazords they have at TRU? Same articulation or better?

2. Is this a new line, or have I already missed one or more? In other words, can I get in from the start, or do I have to go hunt down the older ones on eBay?
