Do you buy gear new, used, both?

Used most of the time unless its not available ( but i'm not in a rush). New for CDPs

I've bought new, used from another person, and demos from dealers....

Both.  New when I was flush, used when my budget shrank.

Also, always new for electromechanical items like speakers, cartridges, turntables, and optical disc players.

Used more for electronics.  Never buy new for AV pre/pros where fast technology makes instant obsolescence.

I only buy NEW. There may be some situation in the future I would buy used but nothing so far!

@fthompson251 Used Cables are the one item I am the most nervous to buy used because there are so many counterfeits on the market. I don't think I would have a problem buying them from a company though such as TMR or The Cable Company. Some of those clones look exactly the same to me and I would be afraid to buy them from an unknown individual unless I knew them.
