Exercise equipment: treadmill/running

I have done a search and have noticed that people have posted looking for a store selling exercise equipment before, but their posts have never gotten any responses.
Where can one buy running machines/treadmills in Taipei?

There are Takasima stores all over. Their stuff is pretty good and not too expensive. I can think of one by the Carrefoure in Nangang and one by the Dominoes Pizza place next to the hospital in Shilin. What’s the name of that hostpital? Not Veterans General. It’s behind the bowling aley on Zhongcheng road.
Another store is called Johnsons; you can see them everywhere too. They are a little more expensive.
