FreeLists / si-list / [SI-LIST] Inexpensive TDR for short/open localizing on a PCB

["Jerry Martinson" <jmartinson@xxxxxxxxxxxxxxxxx>]

Sorry if this seems a bit off-topic.  
 

Does anybody know of an inexpensive and easy-to-use TDR system that's
good enough to localize PCB assembly shorts and open with accuracy that
translates into about 1 inch on a trace?  I'm trying to see if I can
find something that can help out with the old "which chip to replace"
problem during assembly debug as often BGA x-rays are ambiguous.
