newbie with a ep1 dual lens kit here and i will be in japan for a week in Nov.

can anyone advise if there are any stuff worth checking out/buying in Akihabara?

preferably below SGD200 unless it is a super good deal.

i am currently looking for IR filters now, so anything along this line is excellent (adapters??), but not excluding any accessories (i already have a bag and "home-made" wrist strap) and lens (too novice to understand what extra lens i need now, so just throw me your ideas)
