HI Don,
The other side of that coin. I sit here in my home project recording studio looking at most of the gear you mentioned plus a lot more plus 10 keyboards at a total cost of over 100,000. Todays value (ACV), is probably between 5 and 10,000 on a good day with a lot of drunks at an auction.
To add to this sad state of affairs: I am now using only 3 or 4 pieces of equipment for the last year. The rest just sits and (yup you guessed it), depreciates.
One keyboard a year at 3 or 4 thousand is really a great bargain now days.
I just bought the psr9000 new at 1995.00, added a hard drive for 180.00 and a cdrw that I had and it does it all. The rest is sitting. Any offers???
