Where do MPC users find drum kits to make beats for free

Every time I'm online looking at other MPC users who make beats on their MPC they have these really high-quality drum kits that are really hard for me to find on the internet. I've been searching for pages and pages and can't find them. Do you have any clue where these drum kits are on the internet? If you do please tell me.

Well brotha. I guess ill be the first to say you must have the worst search engine skills. You already know free isn't the biggest, or best option for anything your looking for.
But on a side note. most of the sample libraries people sell, offer free demos of the kits they are selling. so if your broke you can get a few drums by going threw all the free samples offered by different companies. if you don't have records or turntables you would need to go the digital route of chopping drums off media files. (wav. or mp3's)

Either way your going to need to put in a little work to get free. Here is a free start in the right direction
