Where to buy (adjustable) dumbells (Saigon)?

Not the kind that are usually plastic and a set weight but the ones where you can add or subtract metal plates (and about how much should they cost?)...figure if I'm gonna pay for a taxi anyways may as well get them at the same time I'm getting the table and chairs.

I didn't see them on that street in D1 where they sell sports stuff (can someone please remind me where that is? The exact intersection so I can write it down for the cab driver would be ideal) but then again I wasn't really looking for them at the time so that might be the reason I didn't see them...

Thanks!

Pham Hong Thai street....(but recently, one store close again, it still few again. Before from Truong Dinh corner to  Ben Thanh market it was full of sport stores (sometimes, one of them closes doors..)).

Corner : Pham Hong Thai street, Truong Dinh street.

(go to the central post office in D1, and buy a map of HCM...it is help you a lot for taxi..).

You show the taxi the place on the map you want to go, and you say :

"Day" (like a beautiful DAY, quite the same pronunciation)

Day in vietnamese signify : "Here"

If the guy doesn't undestand, you can say :

"Toi di den day" (i go there)
(neutral tone, speak slowly, not specific pronunciation).
