Ok, the one I saw was

or

http://www.gwmicros.com/public_html/pages/products/iproducts/BDM_JTAG/Macraigor/BDM-JTAG_Macraigor_Raven.htm

both 818EUR

And their wiggler is 188 EUR.  Yes, most others I see are in the $150 - 
$300 range.

I'm just trying to understand here.  I can see how originally there were 
few (expensive) options, and there was a lot of design and support and 
software creation necessary, so yes, it was expensive.  However from the 
point of view of anyone who is starting a design, be it a starving student 
or a multinational corporation, what do the expensive emulators do that I 
can't do with a $1 DIY one?  Can I get by with a DIY one, or should I 
actually fork out the cash for the name-brand ones?  Let's assume that I 
need to do non-trivial debugging here.

I too am a fan of alternate methods for debugging, or creating modules on 
the PC and then porting them, or loggers, or serial port dumps, however 
there are times when having an ICE makes it a lot easier to figure out.

Thanks for the advice,
