How many people here generally buy used?

I have generally bought new though mostly I try to get the best value for my money which has often been demo gear or last years model heavily discounted.  Effectively a full warranty for a few finger prints. 
Used is something I consider only if I know someone who can fix it!

75 % used, mostly purchased here at Audiogon because i feel that the guy selling gear here is passionate about the hobby and would probably take better care than an EBay seller. IMHO

Just finished piecing together my first 2 channel system and was super aggressive with negotiating prices for used things and getting a good deal. 
Pair B&W CM9 S2 - $600 (some scratches in cabinets but drivers and are pristine and sound quality is unaffected - was bound to happen anyway with toddlers in the house. Yesterday I came home to paw patrol stickers covering the “booboos” on the cabinets)
McIntosh 2205 - $1,500 (in mint condition from original owner, stored in original box for last 20 years, an incredible find!)
2 X 15ft. 12 AWG Sewell cables off Amazon -  $58

Currently just using iPad Pro 1/4” headphone jack into phono input on the amp. In all, I cannot believe how powerful and clear this combo is. After finding these deals it’s going to feel like massively diminishing returns if I ever buy high-end new equipment. I’m sure I will someday, but not until I’m settled in a forever house and kids are further along! 

I do..as long as the seller provides multiple angles of the products and honest about the defects. I also have to check the feedback left for the seller all this time.

Ninety percent new from 1966 until 2000.  Ninety percent used since then.  Began with Heathkits, then Luxman in 2-channel systems.  Went digital HT for about five years in late 1990s, then back to 2-channel analog systems with used Luxman and McIntosh.  Almost all speakers bought used, except for two pairs JBL DD67000 bought in the last four years.  Still have tons of stuff that I never bothered to sell when I “moved up”.  Currently have nine systems set up inside and outside house (we’re isolated in oak forest in Texas Hill Country with no neighbors to disturb), all linked w/ Bluesound.
