Gary,
I can remember buying a Lowry Contempo 80 organ in 76, thinking this is the last instrument I'll have to buy.
I thought that again when I bought a Yamaha 3-manual organ in the early 80's.
Since I've started buying equipment that doesn't break your back (or your life savings) I've been thinking, "This is the last keyboard I'll ever buy THIS YEAR."
