You can find anywhere in town for secondhand stores. You can find shop name with "Je-hwal-yong centre 재활용 센터". So if you want to ask to Korean, you can ask with secondhand stuff as " Joong-go-poom 중고품 or Joong-go mool-poom 중고물품" or secondhand store as "Joong-go Sang-jum 중고 상점".
But problem is that store was quite complicated because some shop selling the furniture only, some shop selling the home electric only. Some of them selling the mixed up with anything. So it will be difficult to find what you wanted.
And price was not that reasonable. Because you will find out that new one wasn't that expensive.
If you didn't buy the stuff with carefulness, it will probably break or explode.

As you can see from the date of writing, I wrote this in 2009.
Now it's 2026.
Things have really changed. Korea now has a widely implemented recycling system, and some people will throw away (through the recycling system) very good conditioned secondhand items.
So items like these will probably go to a secondhand store.
At that time, 중고나라 (the Joonggonara cafe on Naver) was probably the only place.
But smartphones became a thing, and the 당근마켓 (Karrot) app also helped this secondhand market grow a lot.
Foreigners can almost never access 중고나라, but it seems a number of foreigners are using 당근마켓. With the help of AI translation, foreigners can use not only 당근마켓 but also 중고나라, it seems.
I think nowadays you can find more 재활용센터 than in 2009. You can easily find them on Google or Kakao Map.
