Yep, I've had it since before all the clones started showing up.  BTW,
thanks for visiting - I hope you liked what you saw.

While $300 seems high, just think of the cost of not having one in a
production environment :-) Also note that $300 is an order of
magnitude less than typical ICE environments.

Even better are prices like yours, though, an order of magnitude less
than even that :-)

The only thing I don't like about JTAG on the AVRs is that you have to
give up 4 pins to use it.  Other than that, it's great, and worth it's
weight in gold when you are faced with one of those tough bugs.
