Seiko電子拍子機好用嗎？

1) I haven't try this brand before. You may want to refer to the online review.

2) You can purchase it in TomLee or Tsangfook

3) I have no idea about the price. But it's a Japanese brand and it seems quite expensive referring to

the link above.

4) Yamaha and Intelli are quite good.
