stop being lazy im saving for a good turntable, meanwhile a found atleast 5 sites for decent quality mp3 vynil rips .... ok here a litle hint : blogspot vynil
For sample-packs Splice hands down (Landr has some great free ones as well imo)
For sampling real original tracks then there's a site called Tracklib that seems great. You can legally license tracks worldwide (master and publishing) and sample for like 50 bucks which is crazy cheap comparing to clearing real samples legally... They also have exclusive stem-files which is real handy...
Don't sleep on it if you're a sample-based producer!
