....I'm getting really confused about the ruling involving Harpie Lady and Harpie Lady 1, 2 and 3.

Some people tell me that Harpie Lady 1, 2, and 3 are still different monsters, and the rule means that they count towards things like Harpie's Pet Dragon.

Then again, there's people who say that it's just like Legendary Ocean and Cyber Harpie.....since their names count as "Harpie Lady", and because you can only have 3 cards with the same name in your deck, then you can only have 3 in ALL, not 3 of each.

I'm confident in the second ruling....but i've been hearing so many claims to the first one, that I'm not so sure anymore. So if someone could just clear it up one last time, that'd be great.

The name of "Harpie Lady 1", "Harpie Lady 2", and "Harpie Lady 3" is treated as "Harpie Lady" for all purposes, including Deck construction. So you can have 2 copies of "Harpie Lady 1" in your Deck and 1 copy of "Harpie Lady 2", but not 2 copies of each because you would have 4 cards in your Deck treated as "Harpie Lady". This restriction also applies to your Side Deck, so if you have 3 monsters treated as "Harpie Lady" in your Deck, you cannot have any in your Side Deck.

The second ruling is correct. you are allowed three and three only. In any combination of course. So for example your deck can legally have:
1 Harpie Lady 1
1 Harpie Lady 2
1 Harpie Lady 3

not three of each.

Awesome, I'm not an idiot after all :P Thanks for clearing that up in the end. I just hate not being sure of myself and my ability to interpret rules.

The second ruling is correct, the same type of ruling as Legendary Ocean applies to the 3 Harpie Lady as well.

They DO also count towards Harpies Pet Dragon and work with Elegant Egotist and such as well.
