Resale prices for Oppo Digital Universal Players


May I ask the forum to explain to me the disparity in the asking and bid prices for various preowned and some new Oppo Digital Universal Players for sale on Audiogon and on another well known resale site?  I'm seeing prices all over the scale.  I know they're no longer manufactured but the asking and bid prices don't seem to make any sense.  For example, there's a BDP-93 manufactured in 2011 with an asking price is $250.00, another one built in 2010 at $310.00 and another at $150.00 similar vintage.  There's a BDP-95 Blu-ray Universal Player for sale at $643.00.  There's a UDP-205 for $3,000.00 manufactured in 2017.  There's a BDP-83SE that's 10 years old with an asking price of $433.00. There are three new UDP-205s with asking prices from $3,699.00, $4,999.00 & $5,295.00 !!  The UDP-205s new were $1,299.00 when they became available.  There's a new UDP-203 built in 2016 at $820.00......new they were $549.00.  I own a BDP-103 from 2014 purchased brand new at $500.00 and it's still in excellent condition.  What is that worth should I decide to sell it here may I ask?

You dont buy 10-15 year old CD players!! In most cases once the Laser goes you now have a $200-500 doorstop. I sold about 12-15 205's for $2800 - $3200 over the last couple of years. Its called the law of supply and demand.  Your 103 isnt worth much cause it cant be used to make SACD Copies like the 105 can. You can get about $800 for a 105.
Great feedback everyone.  Thanks for your excellent insights and information.   Very interesting and rather unprecedented.  In all of my years in this great hobby of high end audio (40), I don't recall seeing source components sold at higher prices than at their original offerings.  That speaks volumes about the quality and mystique of the OPPO Digital line.  I love riaa_award_collectors comment that you don't buy 10-15 year old CD players.  Absolutely correct yet Ianrmark sold two 10 year old units in a day !!!  It floors me to learn that riaa sold 12-15 UDP-205s at that price range.  Absolutely amazing.  I didn't realize the 105 can make SACD copies.  I do use the 103 to play my small collection of SACDs and it sounds terrific plus I also have a Marantz UD5007.  Both great sources for the $$$.  I use both so that one doesn't wear out sooner than the other.  That's the fun of this business.  It's good to know that sonicjoy's BDP-83 has lasted 10 years.  Excellent info.  
Ya its still working for now. Thats why I bought the CD transport. Hoping the OPPO will last awhile longer just playing the occasional Blu-ray disc.
The Oppo 205s are barely worth their original asking price.  They have an DAC, and weak analog section and power supplies.  The outrageous asking prices for the new Oppos are far above what they are worth.

Don't believe the hype!
I purchased a 205 shortly before they were discontinued based upon all the positive reviews and feedback to replace an aging Sony SCD-777ES. This was the first and last time I will ever purchase a component without listening to it first. I was very disappointed with the sound quality. It wasn’t even decent, let alone great, considering all the professional reviews I read. My old Sony (a great sounding player IMO) was significantly better. While I sat back and thought about how best I could get rid of this dramatically overrated black box, a shocking thing started to happen. The prices started going crazy. The higher they went, the more demand there was. I almost sold it too soon. I held off until prices went over 3k and then I quickly listed it and sold it. What a relief. Not only did I get rid of it, I made an impressive profit. For all of you considering purchasing an used Oppo, don’t, unless you just want it for its DVD capabilities.
