Which should I get?

I'm hoping my parents will let me get a different type of tama. But I can't decide which one I want to beg them for. I'm thinking:

Angelgotchi

Devilgotchi

Connexion

TamaOtch

Arukotchi

Oceangotchi

But I don't know much about them.

First of all, are they in Japanese? If they are, would you need to know Japanese to play with them?

Second, How hard or easy are they? Input from owners needed!

Third, are they fun to play with?

Fourth, what price range are they in? I'm looking for something around or under the $50 range.

Thanks!

um i dunno bout ne of dem cept connexion, its the australian version so its pretty much like connection, oh and dey cost bout AU$25

How much would that be in US $?
