Hello.........I must be a hoarder too! I have only sold gear that is/was new and didn't work out for my liking. Otherwise I still have EVERY piece of electronics available I have used since the late 70s. Of course most of it doesn't work anymore and have become "spare parts". A few still endure.......I still regularily use my Yamaha TX81Z and QX-5 and a Tascam M-06 mixer. I also have a working Alesis HR16, Casio CZ1000, and a Yamaha DX7. Most of the older controller keyboard synths have been given to my Dad who is either still using them or has retired them........he must be a hoarder too!
