How many people here generally buy used?

Mt first used piece was a Crown pre-amp to go with my new Phase Linear 400.  After a 1979 Kenwood TT and Tuner, I have bought mostly used.  I did buy my first Audire pre-amp new, because the factory sales rep, my neighbor, was out of them. All of these have been upgraded with used equipment, which has allowed me to buy a lot of stuff to resell as I found what I liked.  The only amps I tried and sold were a a Sumo Polaris, which has a smallish power supply that lost the bass at high volumes, and an NAD PE100 plus an Adcom, both of which I could have lived with but was I was already spoiled by much better Audire.  I did got through some tuners, including a Sansui TU707/717 which was surprisingly good..

Used 90% of the time. 

As I said in a previous post, I am done buying new gear ~ the audiophile community as a whole takes such fine care of their gear [and does such a great job packing], that I have rarely bought anything that wasn't pretty much like new...I get a big discount, they break it in for me.  Win, win.  And a few times, I've received gear that was so gently used that it wasn't even broken in yet! Buy from trusted sellers on here or other fori, and save thousands...maybe there will be the occasional time that you will wish that had a dealer warranty [which is sometimes transferable from the seller to you], but so far my experiences have been very positive, and our community as a whole is honest and reliable.

Used to buy everything new, but I soon realized that one can find most anything used and in excellent condition. That being said, I do buy new when necessary. Most recently a Bonn N8 and Denafrips Ares II.

90% used and vintage - AG, AK, eBay, USAM, etc.
Only new item was my VPI prime (including speakers and everything)
considering that I have 8 systems (yes i am a hoarder) it i really interesting - you guys just made me think and pause...maybe a few cables were bought new
