The 'Digistrobo' looks alarmingly similar to laser tachs available on the ebay for a lot less than 150.00, such as this one http://cgi.ebay.com/Non-Contact-Digital-Photo-Laser-Tachometer-RPM-Rotation_W0QQitemZ160352588438QQcmdZViewItemQQptZMeters_Testers_Probes?hash=item2555c25296&_trksid=p3286.c0.m14 and many, many more.
After seeing the audiophile version in a catalog, I bought one of the ebay iterations to try-and it does seem to work as advertised-at least, it's accurate compared to my strobe disc. In fact, I made a little stand for it and it has a permanent spot on my tt plinth, ready at a moments notice to check stylus-in-place speed.
I've got a feeling-okay, I know- that this is just another case of audiophile product re-labeling, with the commensurate 6x price bump. Just like most electronic VTF scales.
