No worries, I've been buying Cipher boxes too but I think I got that covered.
Bought them on Nin Nin Gaming, ordered 3 so far, its taking a while but im in no hurry, the prices seemed ok compared Amazon and Ebay.
Only pricier one seems to be the very first box.
But yah Im having issues finding the 2001-2003 TCG Boxes,
Hopefully FireFenrir can help me out with me searchs!
Thanks!
