Cheaper than Bic & Yodobashi

I want to buy a Video camera around Tokyo St. or Akihabara. Do you know any mid-size electronics store with cheaper prices than the big two (BIC C.& Yodobashi)?

The biggest of them all, Yamada Denki, might be worth checking out. Their Akihabara store is not good, but around Shimbashi Station, not far from Tokyo Station, they have two buildings. Their biggest store in central Tokyo seems to be in Ikebukuro, where competition with Bic Camera is especially fierce.

kyon,

I think there are a lot of possiblities, and I wouldn't really call them the "big two" either. For example, this is not about cameras, but my local Kojima Denki carries cheaper laptops than my local BIC. But I prefer to shop at BIC, because I have a lot of points from their card. Just for reference, a lot of locals compare prices at kakaku.com, although I usually find cheaper prices by walking around.

Thank you for your answers.
That website is really helpful, even if I had to translate almost everything to find the location of the cheaper stores.
I think Yamada Denki has the same prices as Yodobashi & Bic Camera.

akihabara electric town, go into the small shops around the exit opposite from yodobashi akiba. if you don't mind used stuff there are incredible deals on equipment there, but even new stuff is cheaper than yodobashi or bic in most of the smaller shops

If you know what you are looking for try kakaku.com

I always buy at LABI/Yamada-denki at Oimachi, one stop from Shinagawa.It's huge, prices are cheaper than Akihabara and they give you lots of points. If you negotiate you can get around 20% on your point card. They have a tax-refund counter too.
