[sdiy] oscilloscope single/dual ?

[Scott Gravenhorst]

I've had both dual and single trace scopes.  Dual wins by a goodly
margin.  Some things can be done with add/subtract, others are not so
easy.  Plus the add/subtract is built in on a decent dual trace, plus the
ability to trigger off of either channel.  

If this is a democracy, I vote dual.
