Anime shops in 日本

Going to Tokyo this summer - anybody care to recommend some good shops for manga and anime-related paraphernalia (ie models)?

Online stores rip you off big time when it comes to ordering Japanese merchandise, either charging much more than the product is actually worth in yen, or just charging ludicrous amounts for shipping even though it still takes a month to reach your house.

Plus, if you're in Japan anyways, you might as well buy some stuff if you were planning on doing so anyways.

Or are you just sore because you've never been to Japan?
