Looks like I never chimed back into this thread after BigDumbWookiee hooked me up with one of these pieces. Though I rarely pick up foreign items, since that's an overwhelming area that I dare not venture into, this POTJ 4-pack was just too cool and unique looking to pass up on. It really is a nice set, that displays well. Obviously not for the "openers" out there though.
I think that aside from the Bonus Pit Droid sets, and one Canadian OTC card, this Mexican set is the only other foreign item I've ever obtained, so that speaks to it's appeal, as far as my personal tastes go. For the packaged collectors, I'd recommend nabbing one if you get the chance. Last I saw, which was quite a while ago, these were still going for relatively cheap - about $35ish. Not bad...
