1. Many 運動店 have, there is one in Amoy Garden if u can't find any other sourse, u can find that.
2. I think answer your third question can help u find the second. Firstly, Are u boy or girl? And what your traget is? If ur a girl, maybe height weight aren't sutable for u, less than 25lbs per side is already enough. But if ur a boy, low weight maybe already suitable for u at the beginning, but uknow? When u keep on trainin' before the result comes, brain would made 腦內啡(endorphin, 具有鎮痛作用的氨基酸), which can make us happy and 鎮痛, and when that time u ain't so easy to stop, and usually we will lift weight hethier and hethier. So if ur a boy, find some changeable dum bell.
3. As the second part answer, if u are a girl, u can buy some dum bells which is unchangeable, that's always cheaper than the changeable one. That's usually under $200. Of course, I saw some 百貨公司 raise the price to $299 even in mainland nowady.
If ur a boy, the one of Goma公司 is quite good, I still am usin' now, even the gym centers like Psysical are also usin' them. There is the $299 changeable and 20lbs per side, pay $140 more can get 44lbs extra weight peice.
So good am I!! I've also found some pics for u: the unchangeable one:
