If it's physical copies you're looking for, Im@s2 PS3 LE will still set you back around 8000 yen.
All the others seem to average out to around 2000 yen or so a pop. So, around 24000 yen if you're looking for physical copies of everything. Then domestic/international shipping.
These are all used prices, by the way. A physical Im@s2 PS3 LE new is around 37500 yen or so, I think I saw?
