bitscope etc

Hi,

Been following the discussion about stepper problems, pulse source
and cable shielding with interest, and I have similar problems. I am
thinking of adding some equipment like the bitscope

http://www.bitscope.com/

perhaps even an affordable oscilloscope if I can find one, to do some
trouble-shooting. For a person who is comfortable with science, but
is not an electronics man would adding those equipment be of any
help? or would I be better off with just a simple logic probe?

Talking of logic probe, anyone has built one themself?

Thanks
