chemical records is what i use if im after something thats pretty mainstream and not too obscure, although if im after somethin rare and proppa bangin that u cant find in any stores i go to http://www.discogs.com but you gotta read peoples feedback and item descriptions before you buy anything, use your greater judgement, ive never been ripped off and ive got some quality tunes from there like dj ricci – the game and max b grant – beeping i definately reccomend it if u cant find something elsewhere. good luck :group_hug
