I have used both the ICD and ICE2000, and both work well.

The ICD has a number of limitations -- it is slower downloading code, it can
have only one breakpoint, it takes up some code space, it has no trace, it
has fewer breakpoint modes.  Given those limitations, it works fine, and you
can debug code just fine with it.

I do not recommend it for professional use in our shop.  If you are paying
people competitive salaries to write code, then your tools don't have to
save very much time on a difficult bug to save more than the price of the
ICE2000.  This is especially true if there are other people twiddling their
thumbs on engineer's salaries waiting for the bug to get fixed.
