I can’t really add anything not already stated but I feel with proper precautions, buying used, which is a journey in itself, is a viable alternative and encourage you to explore it. I generally think buyers/sellers of items for this hobby are mostly upstanding people.
I might have been lucky, but I have had good experiences with all my transactions. Many sellers allowed me to audition the equipment before payment. Many were very interested in sharing knowledge/opinions. Some became friends.
i would concur ... there have been some times when buying or selling used gear have led to nice exchanges and conversations that then have led to very warm friendships.... wonderful when that happens, and in my travels in this hobby over the years, i have made some very nice friendships as a result
sometimes transactions occur (usually purchases) when the seller is dealing with changes in life circumstances, which can be sad, even heartbreaking... as usual, the human stories, journeys, can be touching, it allows us as brethren in this shared passion to show touching episodes of kindness and humanity
at a more every day level, this should remind us to treat others in buying or selling hifi gear 100% in the way that we ourselves would like to be treated
