What is the most amount of money you've spent on a computer or computer-related item?

[Ethan Dicks]

I think the most expensive machine I ever bought (with my own money)
was a VAX-11/725 in 1986.  $4000.  I did it, in part because DEC was
eliminating free license transferrals with after-market hardware
sales.  It looked like my cheapest option to have my own VAX, and for
a time, it was.

If only I had a good option (i.e., under $500, and preferably under
$300) for a disk for that thing that isn't the RC25.  :-P

Runner-up is probably an Amiga 3000 purchased at the launch for full
price (minus a trade-in discount on an old A1000).
