Had anyone built the DIY JTAG debugger?

Got the link to the website somewhere, but essentially it was based
around ATMEGA163, and flashed with the Atmel JTAG firmware.

Just wondering if it works like the $300US real thing.

I'm currently using the Imagecraft AVR C compiler (ICCAVR) for an 'M128
project. It's about as good
as it gets. The "Pro" version ($500 US) I'm using, has full support for
debugging structures 
in AVRStudio. 

For a fresh start project, I'd recommend investing $300 (US) for the
Atmel JTAG debugger.
With the JTAG debugger, AVRStudio you can debug and program your
hardware.

If you choose serial downloading, PonyProg seems to work though you may
need to make or buy a parallel
port dongle. 

BTW, the 'M128 uses the PDI and PDO (UART-0 I/O) pins and NOT MOSI/MISO
for serial download. I made that 
mistake a few years ago on a 'M103 job...
