If you're starting your collection, I'd advise you to go for the normal V2 bronze boys. The golden versions are all limited, despite being shown on anime / manga, and they're more expensive than its normal counterparts. Specially Shiryu, that you'll have some hard time finding it, a friend of mine is selling it on eBay and asking US$ 480.
It's a repinture per se, but it's a different cloth, and it does appear at both anime / manga. That's different when we compare them to OCE versions, that are alternative versions of a same cloth.
I guess Poseidon set will be one of the most beautiful when completed: 7 Marines + 5 PoG bronze boys and Poseidon + 3 bronze boys wearing the golden cloths... It will be PERFECT! Normal bronze boys together with God Warriors and everyone's happy at the end.
