Hi there - I am hoping someone can help point me in the right direction. I have inherited some audio equipment that I know very little about, and I have been struggling to find any info on current prices to look at selling them second hand.

There's a full set of Onkyo speakers, including subwoofer (SL-107) and front and rear speakers (SKF-4600 and SKS-4600), and an amp (TX-SR501).  I think it's about 8-9 years old.  

I also have some Energy, Yamaha, and Sony speakers from about the same period, a Kenwood amp and CD player, and a Yamaha 5 CD changer, a Yamaha centre speaker and modulator.  There's also a Yamaha Laserdisc player.

Sorry if this is in the wrong forum - I am feeling a bit overwhelmed about what to do with the stuff, and have been googling for a while without turning up anything helpful.  As it's older than what is around now, I don't know where to begin to figure out a reasonable price to ask for them. Thanks for any help anyone can offer.
