If you have been spending your time to search for used or new audio equipment, then you probably know that there are not so many places with great classified listings.
IMHO I think that audiogon.com and ebay.com are the best ones, because they have thousands of items in their lists.
But there is a problem - all the time somebody sells something for a great price it's gone for a couple of hours.
So, if you'd like to get something for a good price - you have to spend hours sitting there and looking for just posted items.

Occasionally I've found a tool (web site) that actually monitor audiogon.com listings and other ones for you, so you do not have to sit there all the time.
Take a look and may be it can help you to get a new equipment for less bucks.
Here is a link - http://www.audiowatcher.com

The tool I mentioned here is "Watcher". (you have to register for that , but you can use any email address to get a password...)
