(help) avex fair

[minna]

Ok since it's my ONLY chance of getting past ayu concerts
I can't miss that : avex fair

but my problem is that I can't buy every tour... :'(!!!!

so I need help !
my first plan is to buy My Story & CDL 2005-2006 - I know this is not in the avex fair (well the cdl yes)

what is the cdl difference between limited edition & regular

and after that I can't decide :'(!!!!
I would like to buy the ARENA TOUR 2003-2004

but other than that which one should I buy?
maybe I can buy 3 .. so what d'you recommend?
