Selling home theater equipment questions

What is the communities thoughts on pricing out my audio equipment collection? Onkyo TX-NR1010 1 pair Polk monitor 70 series 2 tower speakers Polk CS-10 series 2 center 3 pair Polk T-15 bookshelves 2 Polk PSW-212 subwoofers 1 pair insignia NS-SP213 bookshelves 1 Sony SA-WM500 subwoofer with isolation spikes Topping TP-21 amplifier

The Onkyo and Polk equipment was set up for roughly 4-6 months and has not been used since we had our third child...No longer have room to set up. The Topping amp and Insignia speakers/Sony sub were used with my computer speaker setup for roughly a year. Is $1000 for everything reasonable or way too much? Granted I don't need to get rid of it and don't mind storing it (I planned on storing it to use down the road anyways) but figured by the time I can set it all up again I'll want separates and to do DIY speakers.
