You can beat that price by ordering an STM32-Discovery kit for about
$12.60. That kit includes an ST-Link MPU that you can disconnect from
the onboard STM32 and connect to your board with 3 wires for the
SWD (Serial WIre Debug) interface. There are jumpers on the Discovery
board to disconnect the onboard MPU. It works. I used it for a while
until I invested in a ST-Link kit. It worked fine with IAR after I
set up C-Spy to use serial wire debug.
I'm getting to be a fan of the STM32 series. Good hardware, good
support tools, a wide range of chips and a pretty good firmware library.
I've started with a lot less on other systems in the past.

Thanks for that! I'm ordering one.

Since this thread started I also found that Segger is offering a Jlink
"educational version" for $60.
From their web site:
"The offer includes free use of Flash Breakpoints. The only limitation
is that it may not be used to develop a product.
...
It is not sold to companies.
...
Even if you are a professional programmer you are welcome to use
J-Link edu for personal interests at home"

The SAM-ICE is a cheaper J-Link, Same H/W, Atmel locked firmware.
It is blue instead of black or yellow, (I happen to have a golden one).

I hear you on that. Mine is an old one, IAR always whines at me that I
am "missing out on advanced functionality".
On a related note, I was very pleasantly surprised this weekend. I was
given an Atmel SAM3S-EK board, and I did not have to do any futzing
with magic macros, custom flashloaders, assorted buggering about with
linker and debugger settings, or anything of the kind - I just set the
target chip in IAR, hit download and it Just Worked. (Exactly the way
I would expect it to work for any device that has all on-chip flash,
btw).
Anyway, something has been significantly improved here. Trying to get
IAR talking nicely to LPC2103 and Atmel SAM7 chips was an exercise in
horror - it seems like the only sane way to do it is to take someone
else's working hello world project and strip stuff out.

I thought they didn't have one that works straight out of the box with
IAR, but didn't check for a long time. Will take a look, thanks.

Cost - Is to have something at home, to avoid carrying too many things
from/to the office when doing some remedial work on weekends.
(And a few personal projects down the road.)
Thanks for the pointer.

Because of performance or because of cost? I see a couple of them on
eBay, fairly recent versions, for $48.
