  They used to be cheap (~$15), but that's long ago...

  I've never had a problem with my A2000, execpt the 4 times I had to
replace one of the 8520's. (Yes, I know I've to switch the computer off
when plugging the printer in or out... :-)

I bought one a few months ago for $14, and that was from a local computer
dealer, not mail order.

Commodore always charges annoying amounts for replacement parts.  The main 
reason seems to be to prevent clone makers from using the parts in competing
hardware.

Not that anyone's making Amiga clones, but there were a number of 1541 (C64
floppy drive) clones.  Nothing C= could do about this, since the 1541 was
made from off the shelf or easy to duplicate parts, except for the actual
ROM code.  When the 1571 and 1581 hit the market, though, they were more
difficult to clone, since they used a hardware serial port rather than a
software driven one.  The 6522 chips used in the 1541 had such a port, but it
didn't work without some heavy external ju-ju applied.  The 6526, on the other
hand, worked just dandy, but is a C= only part (GTE and Rockwell, probably
other too, second source the 6522).  However, at the right price, the 6526
(or 8520, which is the same for 1571 cloning purposes), such clones would be
practical for a low overhead garage shop.  

Anyway, that's the theory behind the cost of replacement parts.
