Do you buy new, used or new or used gear?

I have progressed over the years from buying only used gear to buying mostly new, but I do still occasionally buy used gear if it is in great condition. I tend to take less chances on the age and condition of the gear I purchase now, as I want my gear to be in very good condition for when I eventually want to sell it.  I have had good luck with manufacturer upgrades to used gear, which generally results in having a perfectly working latest/current model and a renewal of the warranty.

About half-and-half in my system.... But I prefer buying used from dealers like The Music Room, with guarantees and returns allowed, than from individual sellers, but I've done that too. 

Typically research for months and then often wait for years when purchasing used - saving and waiting for the right deal.

Main system is roughly 90% used. HT system is used and refurbished. 

New Receiver/TT/Speakers with wedding money in 1967.

Back in the day of VCRs I bought new; TVs I always bought new, current 5.1 is new Sony TV, AVR, Blu-Ray.  The DBX speakers bought new.

Current Three 2 Channel Systems: main, office, garage/shop: ALL used except new low cost DAC in office.

Cameras primarily new, I will buy open box or refurbished by the maker which are variations of new.

Once, 1989, I surprisingly inherited $8k. I bought 3 recently announced Onkyo Integra pieces, Receiver (1st with TV band), Dual Cassette, CD Player. Onkyo rep told me I got the 1st ones to make it into the USA.

Cartridges: mix of new and used.

I restore Vintage, and have been quite lucky to inherit or been given used items.

I mostly buy new stuff but I’ve got nothing against something used if I find a good deal.
