saturday sunday amcorp mall you go lower ground then when you coming down the escalator on your left you will see a guy selling vinyls, his name is Joe and he has quite a good amount of vinyls, i got a few good ones like Greg Howe, Impelliterri, Led Zep, Rush, Yes, etc etc

His collection is quite vast and is reasonablly priced. Just look out for scratches and dents before buying.
