Time for a semi-annual GameCube trade update! (cue trumpets)

Hey there! I'm looking for the following four GameCube Multigame Kiosk Demo Discs:
January 2002
June 2002
25
29
Cases needed for: 17, 22, 26, 27

In exchange, I'm offering to trade other rare/valuable/hard to find GC demo disks. (In a pinch, I'd buy them, but you might get better cash offers -- however, I can probably offer you a fairly good trade!)
