I bought a cheap iaito from this online supplier. I went for the Paul Chen Nami Iaito for just over £138. They have other swords that go above £600 as well.

Oriental Weaponry

They are doing a wide range of discounts at the moment.

I can't give any advice on what to choose unfortunately. You will have to provide proof of being a martial arts student and so on.

At the time of writing, wooden tanto are just £1.20 and a suburi bokken is £4.20. Keep away from the Nunchaku!
