Hello guys! I want to buy an ASIC Miner to start mining. But there on eBay are cheap, with a pretty high hash rate and wich are used. I would buy a used one to save money. Should I buy an used ASIC or a new one? And why? 
Sorry, I'm new in the BitCoin BTC business.

I find them much cheaper on Bitmain, Rockminer or spoodlies.
It depends on what you are trying to do.. IMO mine as a hobby and grab an S3 from kijiji or a "New Rbox" from Rockminer.com
