  <GRIN> What, like a logic probe...? 
I figured if the OP was using an LED as a logic probe, then he might 
not want to throw his filthy lucre after a commercial probe.  It's 
easy enough to toss one together out of hellbox detritus.

  I don't actually have a logic analyser myself
(annoyingly), and tend to 
 reach for my logic probe long before I resort to digging out my 'scope. I 
 find mine indispensible. 
Same here; rather than set up a scope just to see if a line is 
wiggling, a logic probe is much easier. 
on my bench I have a several multimeters [digital and analog], scope,
a pc based logic analyser and a logic proble.  the onder they are used
generally puts the logic analyser last right after the scope.

   If the OP is
in the UK, then Maplins do a nice one for ?15 (which is less 
 than I paid for mine back in 1980). 
Radio Shack used to offer one for a reasonable price, but no 
longer... 
I have one of those and it works ok, I also have one that responds 
to really fast pulses.
