I vaguely remember that there was once a buyer's guide on the forums? Is it still available?
The price guide was removed due to the unpredictability of today's used LD market, we are unable to determine the value of used rigs using a simple mathematical formula at this point in time.
Don moved the list into his LD Companion site.
