True, but you can still find JTAG (w/o ETM) units that sell for
a couple thousand USD.  Abatron's BDI3000 sells for about $3K.
You can't really get started with a Lauterbach JTAG interface
for under $2K-$3K either.  Even the Zylin ZY1000 which is
designed towork with OpenOCD is over $1K.  IIRC, the Mentor/EPI
JTAG interfaces are in the $1K-$2K range as well.

That's not to say that the $20-$30 FT232 USB interfaces don't
work fairly well...

But ARM tracing is not JTAG, it's ETM.  ;)

The exchange rate must be worse than I thought because they go
up to several thousand USD.  If you get one that supports
real-time tracing, you can spend close to $10K without trying
too hard.

For board bring up, the low-end ones generally work fine.

Lot's of cheap JTAG debuggers around. Remember the hardware is cheap, 
but be sure it's supported by the open source debugging platforms.

See 
"http://urjtag.svn.sourceforge.net/viewvc/urjtag/tags/URJTAG_0_10/web/htdocs/book/index.html"
and click on "2.3.3. Supported JTAG adapters/cables"

Buy one of the supported cables.

The MacGraigor Wiggler is very cheap, see 
"http://mcuboards.ecrater.com/product.php?pid=2028415" but you need a 
parallel port on the system for it to work (and not a USB to parallel 
port adapter, though a CardBus parallel port card will usually work. Be 
sure to use XP, not Vista.

"ARM9" is not a chip. Be sure your specific hardware is supported by the 
development system.

Also see "http://www.amontec.com/arm_debug_valuepack.shtml".

JTAG debuggers start from around 30 EUR and go up to several hundred EUR. 
Probably cheaper to buy than rent.  I presume you have a standard ARM JTAG 
connector?  If so you have lots to choose from but it depends somewhat on 
which development tools you are using.
