Which should i get?

[AyumiAi]

I have 150 $ to YesAsia as a gift from my aunt, and so im ordering
the limited edition box for ayumix 7 but i also want to get one of her concerts (overseas version) im down to CDL 2005-2006 or Tour Of Secret 2007
so which one should i get and why? XP dont give spoilers on the costumes and stuff like what they look like (I wait to watch all her performances on DVD so i dont watch them until i have the dvd its more exciting that way xP ) but if she wears a gorgeous dress you can say she wears a gorgeous dress but not like she wears a studded white long bla bla bla dress :3 thanks for the help guys!
