Is there an area in Bangkok where l might find a bunch of shops selling used office furniture, filing cabinets etc?

Can't say l've ever noticed shops selling this sort of stuff but l suppose l haven't been looking before. What price reduction would l expect to find for modern used furniture compared to new? I ask that as sometimes used goods seem to sell for almost the same price as new in Thailand.

I know l could check out the local buy and sell magazines but l'd prefer to have a look around some shops with a range of items.

PS If l was looking for a good pair of used stereo speakers, JBL etc. would anyone have some suggestions where l should look for those as well.

Did you found any shops who sells used office furniture???

I'm looking for used partion walls. So if some one here know, Please let me know

Coming from Sukhumvit: Drive on Ramkamhaeng Rd, take the flyover going over the Srinakarin intersection. One minute after the flyover, it's on your left hand side (a few hundred meters before Carrefour). The place used to be a gaz station. Desks, partition walls, etc...
