Secondlina's Panels

Does anybody reccommend any of the following:

Last Exile
Romeo x Juliet
Haibane Renmei
Avatar - the last airbender
12 Kingdoms

I'd also like to finish watching Spice and Wolf.

I just wonder if these series are good. Reviews on the internet either say *AMAZING* or totally lame. I think these might be hit or miss series... Last Exile looks like it's delicious steampunk. Romeo x Juliet looks like eye candy. Haibane Renmei is well...Beutiful and sad. Plus I already own Niea_7... Avatar seems hilarious and 12 kingdom seems sword-and-cape bonanza. Anybody has a personal review on these?

Also, since the boxsets are really expensive, does anybody know anything about buying them thru itunes? is it expensive? Is it good quality? Anime on itunes, what do we say?

I'm in a serious anime phase right now. Haven't had one this bad since Full Metal Alchemist. I find anime these days lacks a bit of originality but these series seem to bring it back.
