Value of Sony XBR Tube TV's

I have two Sony regular TV's that I'm curious about their value. The first is a 1980's vintage Sony 25 inch XBR tv that sits on the pedestal stand with foot pedals and has two of the four flanking speakers.
The other is a 36inch tube tv XBR. They both listed for $2000 plus when new. Any ideas on whether these old sets have much current value is appreciated.
