Tsubasa Imai 1st tour 23 to 24 Solo concert DVD !!!

Shld i get the japanese version ? Jap version will cost me $70 ..

But if i get the HK version, it will only cost me $30++ ...

But !!! Jap version got the black handphone strap !!!

But !!! It won't be a set if i don't buy Takki's Solo Con DVD ...

And !!! I only intend to get Tsubasa DVD only .. not Takki ...

So !!! Even if i got the hp strap, it won't be A SET !!!

THUS !!! Does it mean i shld get the HK version ???

Which version shid i buy ???
