AVR-Chat

I'd pay $60 for a good one.  By good I mean something that does all  
the bases, handles logical functions, complements, etc. and just  
works out of the box.  Rather than physical transparency, I think the  
real transparency of open source and the ability to add programs or  
features would be the real draw.

Add a place for a small memory card to transfer programs and you'd  
really have something nice.  I might even pay as much as $100 if it  
was really nice.
