Wow, everything posted for sale is ''light use''??

I tend to believe most on this site keep their gear in good shape and these represent fair values used for the most part.

Of course always exceptions.

And sure, sellers always look to put the best spin on a product no matter what or where. Exaggeration is a fact of life, especially when there will be no evidence to the contrary.

Best to deal with those with a good reputation and history of being accurate and reliable whenever possible. I always ask lots of questions before buying used to help gauge. It has worked out pretty well. I have probably participated in a couple of dozen audio related transactions between here and ebay over the last 5 years or so. Only one bad experience on ebay, involving a deadbeat buyer, though that one was a couple of years back and helped tame my enthusiasm for ebay.

"The ads with the high prices that just sit there are another one I can't figure out. I thought they want to sell something, but they won't adjust their prices into reality."

In that case they are clearly fishing for suckers. They want to sell but only if it translates to a big payday and are willing to wait.

"What are the major considerations in evaluating old equipment and what is considered a good price vs the original MSRP."

The same as any other except issues are more likely with older gear so assume that by default until you are able to disprove. Not a bad rule in general.....

Original msrps from years ago are not really that meaningful for determining current value I would say. You have to look at current market prices and establish the true condition of the gear in question, again probably always a best practice regardless when buying.

Can't guarantee audiogon blue book would have much on that model in that many rarer models do not have a lot of data, but for the monthly fee it is generally a good investment. Audiogon blue book is worth having whenever seriously considering buying used expensive gear.

I'm not familiar with that specific Onkyo but Onkyo has made some beauties that also perform quite well over teh years.
