Should I sell my Oppo 205?


Please help me decide. Is there a logical reason for current prices on used Oppo 205? I bought mine few years ago brand new for around $1500. I've hardly used it since, maybe 2-3 Blue rays per year max. I have a pretty good collection of blue rays 4k movies. My questions:

1. Is there nothing else on the market to compete with this relatively old player?

2. What is so special about this oppo ?

3. Is it likely to become more in demand in the future?

Is there really nothing else on market that could perform and compete with this relatively old unit ?
My pioneer elite dv79 is 25 years old. Still the best player ive heard 

keep it in use.     Also have a sherwood cd carousel from the early 2000’s.  Still rocks.  
IMHO, the Oppo was nothing that special, certainly not special enough to command the prices being asked today.  It was a decent player for under $1500.00, but to pay more than that, never.
