Yeah, I just got back from Japan a few days ago and I found some really cheap Macross stuff. At the retail level, especially the smaller stores, if they find that they're not moving the Macross stuff, they'll slash prices big time. I picked up a VF-1s hikaru type for ichi mon, that's 10,000 yen plus a strike armor set for 3,000 yen. This store had piles of them, but I only had so much space in my suitcase.
Another interesting place for Macross stuff is this store chain called "Book-off". I know, sounds weird, but people off-load their used books and magazines here, and they're usually in excellent condition. I found Macross books for 100-200 yen, that usually retailed for over 2,000 yen. Some of these locations even have entire libraries of Hobby Japan.
