Fitness interval timer

I am looking for an interval timer like the ‘Gym Boss’ ones common in North America.

I have looked for them on Ruten and Yahoo but I can’t seem to find anything in English.

If anyone might know some good Chinese keywords to use in the search field that would be great

I’ve posted queries before on the ‘Fitness’ forum but folks just recommended to mail-order one.

Any help would be swell.

Thanks in advance.

I have seen several of these in the electronics plaza at the station 2 stops north from guting on the yellow line, one past dongmen. if you still need it let me know and I will get the details for you.
